My Comments

The last decade has seen the traditional vinyl record gaining a revival as a preferred physical medium to collect recorded music on. But the CD, which has just turned 40 this year, has been simmering along as a collectable music format over this same period and is gaining a similar kind of recognition and acceptability to vinyl.

Some of us still use CD as our preferred physical music medium due to it being cheap on the new or secondhand market or easy to have in a mobile or portable form such as through ripping to hard disk and syncing to our smartphones. As well, the small size of these discs appeals to those of us who want to build or maintain large collections without it taking up much space. Even the record labels have exploited this further by justifying CD as a medium to offer collectable album editions that hold more musical content than the standard album editions, perhaps due to a disc holding extra material or multi-disc compilations stored in a case that is the same size as the standard CD jewel case.

Are we still playing CDs nowadays

This has been more so due to CDs being a cheaper format to replicate and sell than vinyl although able to yield a very-high-quality sound. As well, more of the premium hi-fi brands of respect are giving CD as much developmental and promotional space as vinyl, with this manifesting in component-type CD players that you connect to your hi-fi system appearing in more audio product lineups. Even Yamaha has reintroduced the 5-disc CD changer where all the discs are loaded on to a carousel that is part of a large drawer, in the form of the CD-C603 changer. As well, some consumer-electronics manufacturers are still persisting with CD receivers or stereo systems that play CDs with the former being a component that has radio, CD and, perhaps, network / Internet audio sources which you just connect to a set of speakers of your choice.

I have covered on this site some of the “network CD players” that Yamaha, Marantz and Technics have launched over the years. These combine a CD player and a network-audio streamer in one box, only requiring you to use one input on your amplifier or receiver to play CDs or content held on online sources or your home network.

Marantz have solidified  their position in the network-CD-player space in two ways. Firstly they have released a network SACD player in the form of the SACD-30n with similar features but omitting the HDMI ARC connection. But this time they have released the CD-50n network CD player which follows on from the ND-8006 network CD player that I covered previously.

The Marantz  CD-50n is a CD player with the expectations of a current premium full-width component-type CD player. This includes a mechanism and signal path that is engineered for high-quality CD reproduction and the same kind of advanced CD play functions associated with that format for a long time.

This unit even underscores the “single input on the amplifier” advantage associated with network CD players further by being equipped with an HDMI-ARC connection for TV audio. Here, you would connect the Marantz CD-50n to your TV’s HDMI-ARC connection so you can have the TV’s sound play through your hi-fi system.

Of course, there are the coaxial and optical SP/DIF inputs and outputs that make this unit work as a digital-analogue converter for TVs, MiniDisc decks or other digital-audio equipment; or pass the sound in a digital-audio manner to a digital amplifier or DAC. You can use this network CD player to stream audio content from smartphones and similar Bluetooth-capable devices through it to the connected sound system.

The Marantz CD-50n works as a sound card for computers that are connected to it via USB but some Windows computers will need to run a Marantz-supplied driver to work properly with it. As well, there is a USB Type-A connection for a Mass-Storage device that is full of music held in the common audio file formats.

As mentioned previously, this Marantz network CD player can connect to a digital amplifier or DAC via an SP/DIF optical or coaxial connection. There are two line-level outputs, represented as two sets of RCA sockets on the back. One of these is a fixed-level output typically used with most stereo systems where you have an amplifier that you regulate the sound level with while the other is a variable-level output that can he used with a power amplifier or active speakers. This also comes in to its own in other use cases where you expect the Marantz unit and its remote to be the point of control for the sound level.

There is a built-in headphone amplifier so you can connect a pair of wired headphones to the Marantz CD-50n. But it can serve as a Bluetooth source device where you use a pair of Bluetooth headphones or a Bluetooth speaker as the audio output device. In this case, you have to use the Bluetooth device’s volume control to adjust the sound volume to your tastes. The Bluetooth functionality for both source and target device roles works according to the Bluetooth Classic specification.

As far as your home network is concerned, you can connected to it via Ethernet or Wi-Fi. This leads you to it being part of the DLNA Home Media Network where you can play content held on a media server or NAS. Or through the Denon/Marantz HEOS platform, you can stream a variety of online services like Spotify, Deezer or Tidal, managing them from your smartphone with the HEOS app. For Internet radio, the HEOS platform has support for the TuneIn Internet radio platform so you can listen to a wide range of radio stations including from overseas through the Marantz CD-50n.

Being part of the Denon/Marantz HEOS ecosystem also means that the Marantz CD-50n can work as part of a network multiroom system using other HEOS-capable wireless speakers or hi-fi / AV components made by brands in the Denon-Marantz group. As well, it can be part of the Apple AirPlay 2 or Roon network-audio ecosystems, especially the latter which is seen as the “audiophile network multiroom audio” standard.

If you have a recent Marantz amplifier with the appropriate connections, the CD-50n can be connected using Marantz’s proprietary inter-component control arrangement. This will open up the possibility of single-remote-control operation, one-touch start-up and one-touch shut-down operation.

This player costs AUD$3200 in Australia, but you have a highly-strung CD player and network-audio streamer in one box which may seem to justify the price when you are in to premium hi-fi. Personally, I would like to see more hi-fi companies keep at least one of these network CD players in their product range for those of us who want that single-box solution to a digital audio source in our audio systems.

A Pro-Ject turntable joins the vinyl revival to the home network

My Comments

The vinyl revival is upon us whether you are a young person who didn’t grow up with playing records or an older person who habitually played records on that stereogram or hi-fi system and maintained that record collection. But a significant number of turntable manufacturers have moved away from the purely-analogue “back-to-basics” approach to the classic LP record by bridging digital technologies with that classic music medium.

In a lot of cases, turntable manufacturers have issued at least one turntable model in their range that uses Bluetooth to stream audio from that record to Bluetooth speakers or headphones. Yamaha recently issued the MusicCast VinylPlay 500 turntable that streams the record you are playing through your home network to their MusicCast speakers and amplifiers or plays online sources using a MusicCast app.

But Pro-Ject have come forward with a network turntable that uses UPnP / DLNA to stream the music off that record you have put on to a wide range of network audio equipment using your home network.

Pro-Ject have had a significant hand with the vinyl revival. This is with designing and releasing a value-for-money manual turntable that answers the expectations of “born-again” vinyl enthusiasts and participating in the Australian edition of Record Store Day which celebrates independent “bricks-and-mortar” record stores.

The Pro-Ject T2W Wi-Fi turntable is a belt-drive manual-operation turntable that works with 33rpm and 45rpm records. Records are placed on a glass platter rather than a plastic or lightweight-metal platter, which does a better job of absorbing unwanted vibrations. The tonearm is equipped with a Sumiko Rainier moving-magnet cartridge most likely

Pro-Ject T2W Wi-Fi Turntable press image courtesy of Pro-JectBut this turntable streams the music content over your Ethernet or Wi-Fi home network to any UPnP / DLNA network audio endpoints with it supporting a best-case FLAC lossless audio stream. The Wi-Fi wireless network connection works best case to Wi-Fi 6.

You have to use the Pro- Ject Control App on your smartphone or tablet to set the T2W up for your home network. But this also works as a UPnP / DLNA Media Controller, allowing you to “push” the music stream from your currently-playing LP to a DLNA audio endpoint. The turntable also has a button to “push” the music stream to the last-connected DLNA endpoint so you don’t have to get out your smartphone to do this before you lift the arm on to that album. The Pro-Ject Control App also can allow you to use Sonos or Apple AirPlay 2 compatible equipment to hear that album.

Between the moving-magnet phono cartridge and the Wi-Fi streaming subsystem exists a high-quality analogue split-passive phono preamp which also yields the sound from that album to a line-level input on an amplifier. This would come in handy with music systems that don’t have a phono input that you would typically connect a turntable to. I have done further research and there doesn’t seem to be the ability to run the audio signal to an external phono preamp such as the one built in to that 70s-era hi-fi receiver.

Pro-Ject recommends that you use the control app associated with a UPnP / DLNA capable network multiroom setup to discover the turntable and push its output across the speakers in that setup. This is to assure proper synchronous sound output because one device would be used to “collect” the signal and synchronise it across the different member endpoints in that setup. Pro-Ject doesn’t assure that the T2W’s UPnP setup will lead to proper sync across different devices due to differing buffering capabilities.

This may appeal to people who have an Internet-capable audio system that uses UPnP / DLNA and want to play records through that system via the home network without it being necessarily close to the turntable. But I would like to see Pro-Ject or another company offer similar functionality in a standalone box that can be connected to existing hi-fi equipment.

But I see Pro-Ject’s effort with the T2W as linking the vinyl revival with the home network using standards-based technologies like DLNA. Time to put that record on through the home network!

Chromecast or Apple TV within a public-access Wi-Fi network

Chromecast and similar devices are being used as an alternative to smart TVs

How you can use a Chromecast or Apple TV in that hotel room

There are situations where you may want to use a device like a Chromecast, Apple TV box or a network printer in a place like a hotel that has that headline public-access Wi-Fi network facility. Or you may want to make use of a portable Internet radio to listen to that Internet-hosted radio station at the worksite you are working at which has a public-access Wi-Fi network.

But you will find it difficult to use these kinds of devices on these networks for many reasons.

One of these is that if a public-access Wi-Fi network is properly setup, each device that is on the network is to be logically isolated so that other devices on that network can’t discover your devices. This is more to assure user privacy and data security for all network users.

But this will interfere with arrangements where you need to discover another device that you own that is on the network in order to use it, such as to “cast” media to a Chromecast or Apple TV. It can also interfere with file sharing between two computers or the use of portable NAS devices.

Sony CMT-MX750Ni Internet-enabled micro music system

Sony CMT-MX750Ni 3-piece music system – this has been used to try Internet-radio functionality via a public-access Wi-Fi network

As well, some of these networks are set up with a Web-based captive portal or implement Wi-Fi PassPoint / Hotspot 2.0 or other authentication approaches. This is even if it is about assenting to the terms and conditions of service for use of the public-access Wi-Fi network. Here, these kinds of login experiences don’t work at all with devices that have a limited user interface like a small display or a user interface based around a D-pad. In a lot of cases, you will deal with devices that don’t even have a Web browser at all to work with these captive portals.

I previously covered Wi-Fi mobile networks and how they work. This included the use of travel routers or Mi-Fi devices, or NAS and similar devices that support “Wi-Fi to Wi-Fi routing”.

Travel Routers and portable NAS devices

Mobile NAS as bridge setup

Wireless NAS as a bridge between mobile client devices and another Internet-providing network. This is a similar setup for travel routers that support “Wi-Fi to Wi-Fi” operation.

One approach is to use a travel router or Wi-Fi-capable portable NAS that supports “Wi-Fi to Wi-Fi routing”. This means that the device connects to the public access network while creating its own Wi-Fi network, acting as a router. With Wi-Fi-capable portable NAS devices, you have to enable this function through something like enabling “Share Wi-Fi Connection”. You have to set the NAS so that the data that it has is not shared to the Wi-Fi network it is connected to, something you do when you set up “secure” or “private” operation.

Newer multimedia-ready hotel-room networks

Be also aware that there is an increasing number of network solutions being pitched to hotels and similar lodging establishments that create small home-network-grade Wi-Fi networks unique to each room or apartment. Some companies are even pitching this as part of their public-access Wi-Fi solution or building-wide network / Internet solution for residential or accommodation places like hotels or build-to-rent apartment buildings.

This is achieved through a distinct room-specific network served by a router installed in the room or a VLAN specific to a room or account and operates for the user’s tenure that works like a small home network.

These setups may also be to support a TV or audio setup enabled for Google Chromecast, Apple AirPlay, DLNA, Spotify Connect or other common home-network media protocols. The TV or audio setup is something that a hotelier would like to provide as an amenity to their “switched-on” guests who make use of online services and smartphones for their multimedia consumption. Such networks will typically have a “small-network-standard” Wi-Fi network covering your room or suite and will have an SSID network name and password peculiar to that network.

Most likely, if you do bring along your equipment and have it work with the room-specific multimedia network, you will be able to discover it as long as your computer or mobile devices are linked to that particular network. This could mean that your Spotify-Connect-capable wireless speaker could work with Spotify on your smartphone like it does at home if all these devices are connected to the room-specific network.

You may find that the hotel you are staying in may be set up this way and there could be printed material in your room about this kind of network existing and how to “get on board”. Typically this requires you to connect your smartphone and your devices to the room-specific network once you have activated that network connection.

Your regular laptop computer as a travel router

Your laptop that runs Windows 10 or MacOS 13 Ventura or newer operating systems also offers this same functionality

Laptops that run Windows 10 or MacOS 13 Ventura onwards can offer this same functionality natively. This is infact an approach that I used to run my Chromecast with Google Play as an audio-video output device for my Samsung Galaxy A52s smartphone at the Elsinor Motor Lodge in order to play my music through the motel room’s TV speakers.

Windows 10 onwards

Windows 11 Settings - Network And Internet - Mobile Hotspot option highlighted

Enable the Mobile Hotspot option in Windows 10 or 11 so your laptop becomes a travel router or mobile hotspot

  1. Select “Settings” which is the gear-shaped icon to open the Settings menu
  2. Select “Network and Internet” on the left of the Settings screen to open the Network and Internet window.
  3. Enable Mobile Hotspot whereupon you will see the setup for sharing your computer’s Wi-Fi connection.
  4. To see your hotspot properties, click the “ > “ next to the “Enable Mobile Hotspot” toggle. Note down the Network Properties on this screen which correspond to the SSID (Network Name) and Password for the Wi-Fi hotspot created by your Windows computer.

    Windows 11 - Network And Internet - Mobile Hotspot Settings

    These are the settings you need to go over to make sure your mobile hotspot works. The network details refer to what your devices need to be connected to.

MacOS 13 Ventura onwards

  1. Click the Apple icon at the top left of the screen and select “System Settings
  2. Select “General” then select “Sharing
  3. Look for “Internet Sharing” and click the i nearby that option
  4. Select the network connection that has the Internet service – this could be Wi-Fi or Thunderbolt Bridge.
  5. Select the network connection the other devices will connect to using the “To Computers Using”, which will be Wi-Fi
  6. You then have the option to create a Network Name (SSID) and Password for the hotspot network. Note down the SSID and Password you created for the hotspot,
  7. Once everything looks OK, click Done and toggle Internet Sharing on.
  8. Click Start in the pop-up message to confirm Internet Sharing.

Setting up your devices

Then, set up your devices like your network media player or network printer to link to the hotspot network you created in the above steps. Most network media devices will require you to go through the “manual Wi-Fi setup” process with some devices, especially speakers, requiring you to link to a “setup” Wi-Fi access point integrated in the device and running a setup Website hosted by that device.

That also means that your smartphone or tablet has to connect to the hotspot network if it is to benefit from the devices that you connected to that network. This would be important for media-sharing protocols like Chromecast or DLNA, or network-printing protocols like AirPrint or Mopria.

When you are finished

If you are using Windows or MacOS as a travel router, turn off the “Mobile Hotspot” or “Internet Sharing” functionality before you pack up your equipment. This is to assure secure operation and also saves on battery power for your laptop computer. With a travel router or portable NAS, you just simply disable the network-sharing functionality when you pack the equipment up.

Remember that the settings will stay the same for your Mobile Hotspot or Internet Sharing functionality so you don’t need to connect to a new Wi-Fi network if you use the same method again. This also holds true for travel routers or portable NAS units that implement network sharing.

In the case of that multimedia-ready hotel room network, you will still have to connect your equipment including your computer or mobile devices to these networks when you set yourself up in your room. This is because the guest credentials are likely to change as a means of protecting guests’ own equipment and experience.

My Comments

Samsung is launching two computer-monitor models that have Smart TV capabilities. It is similar to the likes of LG offering some computer monitors with integrated broadcast-TV tuners.

Good enough for that personal space where you work and live in

This class of computer monitor addresses use cases where one would put one of these monitors to service not just with their computer for work or advanced gaming but also for ordinary entertainment purposes. The classic examples of this use case include a bedroom or den that serves as one’s office and personal space; or a person who moves in to a small apartment or bungalow where one large room serves as their living room, dining room and office.  It also includes university students who live on campus in a student-accommodation facility like a dorm or residence hall or workers who live in employer-provided accommodation facilities as part of their job.

I did some previous coverage on this topic in an article about having a TV serve as a computer monitor or using a computer monitor as a TV and nowadays some TV manufacturers are offering large-screen TV models that are optimised for computer games with the video electronics equivalent to what is offered in a current-spec gaming monitor. This is due to a realisation that one could be bringing that Windows-based gaming rig or that current-spec games console in to the living room to play games on the big screen TV.

But the Samsung M7 (32” 4K UHD) and M5 (27” or 32” Full HD) monitors have Samsung’s Tizen-OS-based Smart Hub smart-TV platform. These include access to apps for locally-popular video-on-demand entertainment services delivered through that platform. Both sets connect to your home network via Wi-FI 5 technology and they support peripheral connectivity via Bluetooth 4.2 or USB. The Wi-Fi functionality even goes further to work with Wi-Fi-based mirroring technologies and allows the monitor to be part of your DLNA Home Media Network. As well you can stream audio and video from supported Apple devices using the AirPlay 2 protocol.

There is even support for Samsung’s Wireless DeX capability where your Samsung Galaxy S8 or newer Android phone uses the TV as a desktop-style interface. Add to this a virtual-machine which works with Microsoft Office so you can work with Office-based documents stored in the cloud.

The monitors have a remote control so you can manage the smart-TV interface in a “lean-back” manner. This even has the ability to work with the Samsung Bixby voice assistant thanks to a microphone integrated in the remote control. As well, they have two HDMI inputs that support HDR10 and HDMI-CEC. That means you have room to connect your computer and another video peripheral like a set-top box or games console. The M7 model also has USB-C with 65W Power Delivery, Display Port alt connectivity and USB-hub functionality to boot.

A question that will come up is whether the monitors will have an integrated broadcast-TV tuner of any sort. As far as I know, they don’t have that kind of feature although the initial models are being launched in to Canada, the USA and China. But this may be a feature considered of importance for customers in the UK, Europe, Asia, Australia and New Zealand. This is because these countries place significant importance on access to free-to-air TV especially from their national public-service broadcasters.

On the other hand, the DLNA ability that they offer may work hand in glove with broadcast-LAN boxes and PVRs that support this standard. Or Samsung could build SAT>IP client support in to these monitors where they are targeted to British and European markets at least. This is due to this standard being supported for satellite broadcast-LAN devices and, in some cases, terrestrial and cable TV within those markets.

But what I do see of Samsung’s effort with the M7 and M5 monitors is that they are maintaining interest in the market niche where a computer monitor is expected also to serve as a TV for entertainment purposes. This market niche can be further supported through having a wide range of these types of monitors including some game-ready variants and units that can work well with multi-display setups.

Now it’s 3–Technics now premiers their own network CD player

Energize music from multiple sources with the Grand Class Network / Super Audio CD Player: SL-G700 (Press Release)

My Comments

Over the past few years Yamaha and Marantz have put forward a relatively-new type of hi-fi component unit in the form of the network CD player. These are CD players that connect to your home network to play audio content hosted on equipment on that network or on an online service.

A core advantage these units have is you only use one line-level input on your amplifier or receiver to serve one piece of equipment that plays a CD or to listen to an online audio service or something held on your network-attached storage device. They also fit in well when it comes to upgrading or replacing an existing CD player that you have and you want to benefit from your home network and online audio services.

For a long time, Technics was the hi-fi arm for the original Matsushita (National Panasonic) brand, offering value-priced and premium hi-fi equipment such as the legendary SL-1200 series of DJ turntables. It was while they were applying itself to musical instruments made by Matsushita. This brand even started the idea of the main Japanese consumer-electronics names running a separate brand for their hi-fi equipment through the late 1970s and early 1980s.

But through the late 1990s and the early 2000s, Technics evolved itself to the musical instrument and DJ equipment market while having value-priced audio equipment under the Panasonic name. A few years ago, they rebuilt the hi-fi image by focusing on equipment destined to the high-end hi-fi market with them supporting vinyl, optical-disc and network / online delivery.

Now Technics have come to the fore at CES 2019 by premiering the Grand Class SL-G700 Network SACD player. This is a network CD player that is optimised for audiophile high-end listening by providing full playback of SACD discs along with file-based or CD-based audio content based on the high-end MQA standard. Here, it is infact the first network CD player to provide full playback of SACD discs.

This unit’s digital-to-analogue path has been worked on through the use of premium DAC circuitry that is built with a dual-mono approach. It is as if two digital-to-analogue signal paths are created within the unit – one for the left channel and one for the right channel.

It also includes circuit-based isolation to prevent digital-processing noise from creeping in to the post-DAC analogue signal path. As well, a separate digital-analogue signal path exists for the unit’s headphone jack. There is an operation mode that effectively provides SACD/CD direct sound when you play a regular CD or high-end SACD.

As far as I know, the network aspect for the Technics SL-G700 network SACD player supports Bluetooth and Wi-Fi. There is support for AirPlay and Chromecast audio streaming from iOS, MacOS or Android devices. It also has access to Spotify, TiDAL and Internet radio online services.

What I see of this player is that it is another brand’s attempt to focus the network CD player towards the high-end audiophile market who may be maintaining their CD collections but make use of online music services. This is more so if the premium amplifier that they use has as few line-level inputs as possible.

What are the full-featured desktop NAS units about?

My Comments

Increasingly Synology and QNAP have become strong rivals when it comes to full-function network-attached-storage devices that do more than what WD, Seagate and others offer. Here, they are made by two NAS specialists who are running high-end NAS-focused operating systems that can be run headless or with a screen and keyboard “head”. Some manufacturers like NETGEAR and ASUSStor are following on with Synology’s and QNAP’s efforts to join in the pack when it comes to

QNAP TS-251 2-bay NAS

QNAP TS-251 2-bay NAS – another example of what a full-function NAS is about

offering full-function NAS units for home and small-business use.

Recent iterations of these devices typically have the same kind of computing power as a relatively-recent low-end regular personal computer but put this power towards file handling and serving. Most of them will support at least a two-disk RAID setup in the low-tier varieties with the mainstream models having four or five disk bays for a RAID 5 setup. The “brain” in these devices will be mostly an ARM-based CPU but higher-spec variants may use an Intel or AMD processor expected in a very low-end laptop computer. You may also find some NAS units like the Synology “play” NAS units running a graphics processor as a co-processor for media transcoding. A significant number of models will even support upgradeable RAM to allow them to work more quickly and handle more data traffic.

But the operating system is of a similar standard to one that would drive a regular personal computer. Most likely it would be a variant of a desktop Linux distribution and would be regularly updated as well as allowing users to install apps from the NAS vendor’s app store. Once you log in through a Web-based user interface or a keyboard / screen / mouse “console” attached to the NAS, you would experience a user interface similar to Windows, MacOS or desktop Linux running a graphical user interface.  But most of these user interfaces can’t allow for cut-and-paste between the host computer and the NAS user interface.

The apps will typically convey particular file-handling functions like syncing to online storage platforms, BitTorrent server functionality and DLNA-compliant media-server functionality. There is also apps that “tie” the NAS to native mobile-platform client apps supplied by the vendor to allow transfer of data between the NAS and a mobile-platform tablet or smartphone. It is typically a way to push a NAS as a “personal cloud” by working with a vendor-hosted “DNS-mapping” arrangement to allow you to upload content from your iPhone to your NAS even while you are out and about and connected to the Internet. This is in addition to various “client-backup” server tools for regular-computer platforms along with NAS-NAS backup tools.

Let’s not forget software like media-player functionality or IP-camera videosurveillance recording functionality. In some cases, there are various server apps for email or WordPress content management so you could easily purpose these units as a business information server. In some cases, adding peripherals to these NAS devices opens up paths for extra functionality with, for example, TV-tuner modules converting these NAS units in to Tivo-style PVRs that can share live or recorded TV content over the network.

QNAP’s QTS and Synology are very similar in many ways but Synology is focused towards simplified operation while QTS is focused towards taking advantage of faster better hardware. There are other similar full-featured NAS platforms like Netgear’s ReadyNAS or the ASUSStor NAS platform existing but there doesn’t seem to be the same kind of third-party developer base built up around these platforms.

But what can be done to make the full-featured NAS market better? One approach could be to allow the licensing of one or more of these NAS operating systems and app platforms to other companies on a “white-label” basis so they can launch their own full-featured NAS product range. This can avoid the need for a company who wants to develop their own NAS product to “reinvent the wheel” when building software.  As well, the creation of one or more large platform bases for NAS operating systems can give software developers the confidence to create software for these devices. Therefore it can avoid the home and small-business NAS market becoming like the games-console market which is focused towards vendor-specific solutions with a limited path for delivering additional software.

Personally, I would recommend the full-function NAS units of the Synology or QNAP ilk as being suitable for those of us who want more out of a network-storage device. In some cases, I would see it as appealing for an upgrade path for people who see their NAS device do more than just host files from your computer and share them to your Smart TV. Similarly it would appeal to those of us who want the basic abilities like DLNA media serving to be done in a more capable manner.

Marantz answers Yamaha with a network CD player of their own

My Comments

Previously, Yamaha identified a product class in the form of a full-width network CD player which can either play CDs on its own CD transport or network and Internet sources obtained via your home network.

This product has filled a market niche with people with a hi-fi system equipped with an amplifier or receiver that doesn’t have enough line-level inputs for a network media player and a regular CD player. As well, these CD players can allow a person who is upgrading or replacing a CD player to benefit from the extra network-audio-playback functionality by simply swapping out one device.

It was very similar to what had happened in the MiniDisc era of the late 1990s where Sony, Sharp, JVC, Marantz and others offered a CD/MiniDisc deck as part of their product lineup.. Here, these full-width units housed a single-disc or multi-disc CD player and an MD deck in the same housing and you could simply hook these units up to your amplifier’s or receiver’s tape loop for CD or MiniDisc playback or to record to the MiniDiscs. In some cases, I saw these units as effectively “modernising” old stereo equipment by allowing you to add CD and MD functionality in one action. They also appealed to music playout setups for churches, theatres and the like due to being able to occupy one input on the mixing desk for a regular CD or a MiniDisc which appealed for having pre-recorded material “ready to play”.

As well, it was also similar to the popular DVD/VHS combos where these units were a single box that only took up one input on your TV to be able to play DVDs or VHS videocassettes. In a lot of situations through the late 90s and early 2000s, these machines became the preferred way to add access to the new DVDs and the old videotapes when it was time to set up new TV equipment or replace a broken-down video recorder.

Subsequently Yamaha offered a follow-up model to the CD-N500 network CD player in the form of the CD-N301 which omitted USB connectivity but was “Wi-Fi ready”. It was also offered in the black finish as an alternative to the traditional silver finish to complement hi-fi setups that mostly have black-finished equipment.

This year, Marantz have answered Yamaha by offering a high-quality network CD player as part of this year’s hi-fi product lineup. It was as though they were following on the legacy of their CD/MD decks, especially the CM-6200. The ND-8006 offers the high-quality CD playback that Marantz is known for and this applies to regular CDs as well as file-based CDs full of MP3 or WMA audio files. There is also the ability to play from USB Mass-Storage devices with this unit handling all the common audio file types including FLAC.

But it can connect to your home network via Wi-Fi or Ethernet technology and uses this connection for a variety of applications. This includes access to Spotify, Amazon Music, TiDAL and Deezer “online jukeboxes”, and Internet radio via TuneIn Radio in the context of online audio services. You can stream audio content from your Apple devices or iTunes using AirPlay; but can play content held on your DLNA-capable NAS or media server. The Spotify functionality even supports Spotify Connect playback where a Spotify program tied to a Spotify Premium account can effectively become a controller with the music emanating from the Marantz network CD player.

There is some level of functionality as far as the Denon-Marantz HEOS multiroom system is concerned. At least you could set things up to stream a network or online source across multiple HEOS-capable speakers or amplifiers existing on your home network including the amplifier or speakers this CD player is connected to.

You can use the Marantz ND-8006 network CD player as a high-quality digital-analogue converter for SPDIF PCM sources connected via Toslink optical or RCA coaxial inputs, which would come in handy with a smart TV, set-top box, DVD/Blu-ray player or MiniDisc deck. Or it could serve as a “virtual sound card” for your computer thanks to a USB Type-B input. There is even the ability for this CD player to stream audio content from your Bluetooth-capable smartphone or other device.

The Marantz ND-8006 network CD player is another example of the hi-fi digital-audio equipment where the manufacturer has invested heavily in the playback sound path in both the digital and analogue domains. The digital-filtering job is looked after by the “Marantz Musical Digital Filtering” circuit which was a home-designed circuit optimised for music quality. Then the digital-analouge conversion job is looked after by a ESS9016 Sabre digital-analogue converter circuit.

Let’s not forget that this network CD player can play “master-grade” digital audio files from USB storage or your home network’s DLNA-capable NAS. It also includes the ability to enqueue any of these files for subsequent play when the current one is finished, similar to building up an “Active Queue List” on some MP3 players. It can also convert “master-grade” digital audio presented over an SPDIF digital audio link.

As far as connecting to your equipment is concerned, you have a fixed-level analogue line output along with a variable-level analogue line output. Marantz even suggested using the variable output as a “pre-out” for connecting directly to active speakers (think Bose Acoustimass or B&O Beolab speakers for example) or a power amplifier. There is also SPDIF digital outputs in coaxial and optical form for connecting to a home theatre receiver, digital-analogue converter or digital amplifier based primarily around discrete componentry.

There has also been some investment in the headphone amplifier which caters for those of us who use high-quality headphones for private listening. Like most other full-width hi-fi equipment, this will require the headphones to be equipped with the traditional 6.35mm stereo phone plug.

Although the Marantz ND-8006 network CD player has a price within “premium-equipment” territory, it is more about being able to answer this product class at the premium level. What would need to happen to build out the network CD player as a product class would be to have other value-priced hi-fi names offer these products as part of their lineup.

My Comments

Previously, I had touched on the issue of availability of “full-width” network-capable stereo receivers that have the same expectations as the traditional hi-fi receiver that has been seen as the heart of many hi-fi systems. This was when I had called out the Onkyo TX-8050 network stereo receiver and the Yamaha R-N301 network stereo receiver.

Here I was focusing on people who value the idea of creating a hi-fi system that is about playing music rather than a home-theatre setup that is about showing what Hollywood has to offer. Situations that I think of include creating a formal lounge area where you want to focus your activity on entertaining guests, reading and playing or listening to music; or simply maintaining a separate home-entertainment system optimised for playing music.

Yamaha are still pushing through with stereo receivers that can connect to your home network. The latest examples are underscored with the R-N602, R-N402 and R-N303D Natural Sound Network Receivers which integrate the concept of the stereo receiver with the home network and multiroom audio thanks to the latest iteration of the Yamaha MusicCast network audio technology.

This technology that Yamaha implements in these receivers isn’t interlinked with any overarching multiroom network-audio standard adopted by many manufacturers. But they can also work with network audio sources like DLNA-capable media servers including NAS units, or online sources like Spotify or Pandora. Those of you who use an Apple device running iOS or a recent iteration of MacOS can also use these Yamaha receivers for your device’s audio output.

One of the features I am calling out is the ability to stream audio from a source device connected to these receivers to other Yamaha MusicCast devices. For example, in the case of the R-N602, you could start a record playing on the turntable connected to this receiver in the formal lounge room. Then you use the Yamaha MusicCast Controller app on your iOS or Android smartphone to hear that record through the Yamaha PLUS (WX-030) speaker in the kitchen.

Similarly, these receivers are implementing Bluetooth not just as a source but as an alternate output. For example, one could hear a local radio broadcast on the receiver’s integrated tuner through their Bluetooth headphones without the need to worry about the length of their headphone cord thanks to this functionality.

The Yamaha R-N602 does cater very well for legacy media by providing an integrated phono stage for a turntable equipped with a moving-magnet cartridge, as well as two tape loops which can come in handy if you still record to tapes or other media, including using a computer to archive old recordings. But the Yamaha R-N402 and R-N303D has its analogue inputs being line-level only with one tape loop.

At least Yamaha haven’t forgotten about the network-capable stereo receiver as a product class for devices that serve as a hi-fi system’s hub. Instead, they have made sure that there is a range of equipment that suits different needs and budgets, allowing us to consider how to build out that music system as we want.

Setting up a mobile NAS to work with your home network

WD MyPassport Wireless mobile NAS

The WD MyPassport Wireless mobile network-attached storage – can offer data to the host Wi-Fi network when set up in hotspot mode

Increasingly, data-storage device manufacturers are adding to their mobile network-attached storage devices the same kind of network-based data storage and access features typically offered with a standard desktop NAS device. This is rather than these devices just being a lightweight file server for smartphones and tablets connected to the device’s own Wi-Fi access point.

I had previously reviewed one of these devices in the form of the WD MyPassport Wireless mobile NAS which demonstrated this kind of functionality. In the review, I had called out the DLNA-compliant media server that was part of that mobile NAS’s feature set, where you had the ability to show your photos and videos on one of the latest Smart TVs via the home network the TV is connected to.

Mobile NAS with hotspot mode set for “secure” or “private” mode

As well, some of the increasingly-sophisticated devices like the WD MyPassport Wireless Pro also are offering the same kind of Samba-based (SMB / CIFS) file transfer method that you can do with other NAS devices so you can transfer resources to these devices using your regular computer’s operating-system’s file manager and its network file transfer protocols. Similarly, the devices may implement FTP, WebDAV or other common network-file-transfer protocols primarily to allow you to upload photos and footage from your Wi-Fi-capable digital camera or camcorder to the mobile NAS if the camera honours these standard protocols.

How to have this work properly?

Here your mobile NAS unit needs to be set up for connection to an existing small Wi-Fi network as a client device of that network. It also needs to be set up to share its resources to that client network in addition to the network it creates using its own wireless access point.  Most of this configuration that I would be talking about here would be something you would do using the vendor-provided native mobile-platform app or, perhaps, a Web page that the mobile NAS creates as its management page.

Mobile NAS with hotspot functionality set up for file sharing mode

Typically, you may set this up as part of enabling a “Share Wi-Fi Connection”, “Wi-Fi Hotspot” or similar function that effectively shares a logical network connection between multiple devices that connect to the portable NAS’s access point. This function is similar to what most travel routers offer as a way to share the one logical (and usually permitted) connection to a hotel’s guest-access Wi-Fi service amongst the personal computing devices you and your travelling companions own. Similarly, this same function creates a “trust circle” between multiple devices connected to the mobile NAS’s access point allowing them to be discovered by each other even if the public-access Wi-Fi network that the NAS is connected to is configured properly with client isolation enabled.

When you enable the “hotspot” function on a sophisticated mobile NAS like the WD MyPassport Wireless / Wireless Plus series or the Seagate Wireless Plus, you will have an option to set this function to work in a “private” or “secure” mode or a “sharing” mode.  In the “private” mode, the data held on the NAS becomes available only to devices on the Wi-Fi network created by the mobile NAS’s access point. Conversely, the “sharing” mode will make the data available to devices on the network which has the Wi-Fi segment you connected the mobile NAS to as part of the “hotspot” mode.

Availability of data held on mobile NAS Sharing mode Secure / Private mode
Host wireless network Yes No
Wireless network created by mobile NAS’s access point Yes Yes

To allow the mobile NAS to share its resources on your home network, you need to enable the “sharing” mode or disable the “secure” or “private” mode while setting up the “hotspot” functionality. It is a wise practice not to use the “sharing” mode on a Wi-Fi network used as a public-access network and this function wouldn’t work with these networks that are properly set up with client isolation enabled.

What can the manufacturers do to improve the Wi-Fi bridging functionality on these devices?

The “Wi-Fi hotspot” or “Shared Wi-Fi” functionality could be improved upon by allowing users to create preset operating modes for particular Wi-Fi networks. This would work in a similar way to the way Windows allows the user to classify each network they connect to as being a “home”, “work” or “public” network, causing it to adopt an exposed persona suitable for your home or office network or a private person for that public-access Wi-Fi network. Such parameters could be to determine whether to share resources with the host network or to always clone the client device’s MAC address when connecting along with remembered Wi-Fi network passwords.

Here, as a user connects the mobile NAS to a Wi-Fi network for “Shared Wi-Fi” operation, they are invited to save the configurations they have established for that network. Then, when they reconnect to that network, the mobile NAS assumes the operating modes that the user previously defined. These details can be referenced by the host network’s ESSID or a user-defined name for that network.

Conclusion

Once you know how to set up that highly-capable mobile NAS device and exploit the “private” or “shared” operating modes that these devices offer with setting up the “Shared Wi-Fi” or “hotspot” mode, you can then use them to make resources held therein available to other small networks you connect them to.

Photos not the right way up on your TV?

Media contents in Dropbox folder available on DLNA-capable Samsung smart TV

Pictures that are copied in using Windows Explorer may not always appear the right way up

A problem that can surface with some photos that you view using your Smart TV, set-top device or similar equipment is that they don’t appear the right way up.

It happens more so with those pictures that come in from an email whether as attachments or downloadable links, or from a cloud-storage service. Similarly it also happens if you transfer the pictures from your device to your computer using the operating-system’s file manager i.e. Windows / File Explorer or MacOS Finder by using the file-copy procedure. This latter process is something most of us do when we want to make digital pictures that we took at someone’s location available on their computer.

These cameras record information about the photo orientation as part of the picture file when you click the shutter

The main problem is that today’s cameras and mobile devices record the orientation of the photo in the file that represents the image as part of machine-readable EXIF metadata. Most of the file managers recognise this metadata and use it for creating the thumbnail that is seen for each file. Similarly, when you upload photos to an image-sharing or social-media site, you will find that these pictures will be shown the right way up thanks to this metadata. It is also true of image management software which even creates copies of the imported files that are the “right way up” as part of the image-import process.

Windows 10 File Explorer

Copying photos from your camera using Windows / File Explorer or other file managers may not guarantee the best results with photo-rotation metadata

But a lot of hardware media players like smart TVs, set-top devices and electronic picture frames don’t recognise this EXIF picture-orientation flag and show the picture with the incorrect orientation. It can be exacerbated with DLNA media-streaming setups where the DLNA media server doesn’t use this flag to rotate the picture to the correct orientation when it is being served to the client device. The same problem also extends to some photo-viewer and presentation software that doesn’t understand the EXIF photo-orientation tag properly.

Another situation that always surfaces with photo orientation is if you are photographing something on a table, floor or similar horizontal surface. Here, the camera or smartphone doesn’t properly register the orientation due to the orientation sensor being driven by gravity. In this situation you would still have to manually rotate the image even if you were importing it with software that understood this EXIF orientation metadata.

How can you work around these problem when you want to show images that are drawn in from email or copied over from that digital camera?

Cast To Device option to show picture on DLNA video player – may not always work properly with the EXIF photo-orientation metadata

One way would be to open each portrait image using a photo editor or bitmap image editor that understands the EXIF photo-orientation tag like Windows Paint or Adobe Photoshop, then save the image as a JPEG file using the software’s Save As command. This will typically rotate the image the right way up and strip off confusing EXIF tags. It would appeal to situations where you are preparing a folder of photos to be shown, perhaps on a USB stick or using “Cast To Device / Play To Device” on your Windows computer and a DLNA-capable video device.

For Windows users, especially those who regularly copy photos to their computer using Windows Explorer / File Explorer, there is a free program that can batch-rotate photos in a folder correctly. The program is called JPEG Autorotate and is freely available from its author’s site. Once installed, it appears as a secondary-menu (right-click) option to allow you to rotate a single image or all the photos in a folder including the subfolders without quality loss.

If you are using a computer as the primary storage or “staging post” for your digital image collection, the best path is to use the photo import functionality that is part of the image management software installed on it. Typically this will be Windows Photos, Windows Photo Gallery or Photos for MacOS (formerly iPhoto) that will be with your operating system. As well, make sure that the “rotate photos on import” option is selected in your software’s import settings.

This information will help you with making sure that digital pictures appear the right way up no matter the device you are using.
