I am reviewing the Sony STR-DA5500ES high-end home theatre receiver which is the first network-capable home-theatre receiver that I have reviewed in my blog. At the moment, Sony have supplied me with the SRS-DB500 2.1 powered speaker set which I will be reviewing in a separate article on this blog, for use with this receiver.

Some of you who may not understand sophisticated audio setups will benefit from a reference page which will explain the terms that I will use when describing this receiver and other audio equipment in this blog.

This unit is the second model down from the top-of-the-line STR-DA6400ES receiver in Sony’s high-end “ES” range of home-theatre receivers but is still very capable in its home-theatre-hub role.

Fit and finish

This receiver has the same fit and finish associated with the good-quality Sony hi-fi equipment that has existed for many years/ The controls are smooth and properly responsive and the unit’s finish looks “very polished”.

Usability

This unit excels on useability in a similar manner to most Sony home AV equipment that I have used.It has that very bright vacuum-fluorescent display that is easy to read even at dim levels and the controls are easy to manage.

Normally comes with two remotes – one with many buttons for controlling a home-theatre system’s components and for full control of the receiver; one for GUI-based control of the receiver.

Connectivity and Flexibility

This high-end receiver excels in this field of connectivity and flexibility. There are seven 120W power amplifiers built in to this unit’s chassis. You can set up a 7.1-channel speaker setup so you can properly enjoy movie content on Blu-Ray discs that is mixed to a Dolby Digital EX 7.1-channel sound-mix. On the other hand, you can set up a 5.1-channel speaker setup for Dolby Digital 5.1-channel sound-mixes commonly on digital TV or DVD and use the two spare power amplifiers for different setups.

Firstly, you could have speakers in another room to play another stereo sound source to that room or set up a sophisticated “bi-amp” setup where the tweeters and woofers in a capably-wired pair of front speakers are amplified separately. The limitation with this receiver is that there isn’t the ability to have the crossover functionality or the amplifier levels managed in a bi-amped setup.

An example of very good connectivity options

The multi-zone feature also allows for yet another zone to be catered fro as an audio-only stereo zone but with its own amplifier. Similarly, the secondary zone can be amplified with another amplifier. The line outputs for the extra zones are in fact line-level outputs that are independent of the main volume control and you would have to adjust the sound at the remote amplifiers.

These setups also allow you to “scale up” your sound system as you see fit and can afford the extra equipment. You can even start with a pair of good stereo speakers and, as you can afford them, connect up extra speakers for your surround-sound setup.

There are plenty of audio and video inputs for extra audio and video equipment, Music enthusiasts are even catered for with a phono input for a good turntable as well as two tape loops for recording devices like cassette or MiniDisc decks. These same connections can be used for connecting up a computer’s sound subsystem for recording vinyl or cassettes to the hard disk rather than using those poor-quality USB turntables. Those music enthusiasts who believe that the audio reproduction of a dedicated CD player connected to the analogue inputs is better than that of a DVD or Blu-Ray player connected to the HDMI or optical digital inputs of this receiver can connect the CD player to these inputs.

The front panel provides walk-up connections for 1 regular video source (composite video, stereo analogue audio and optical digital audio) and 1 HDMI video source.

There is a DMPORT connection for use with optional Sony-supplied modules that provide connection to and control of various portable devices. These include Sony Walkman MP3 players, phones that have Bluetooth A2DP functionality like my Nokia N85 as well as Apple iPods and iPhones..

For video displays, there is connection for two HDMI-equipped video display devices so you can run a projector or smaller “operator-console” LCD screen alongside the regular large-screen LCD or plasma display. The receiver also supports video-signal conversion from regular video signals to HDMI signals, which means no need to connect composite or component cables to the main display to gain benefit from legacy video sources.

Network AV

The receiver offers some network-enabled functionality but this is limited to playback of DLNA media content with the user controlling the receiver through its remote control and requiring the video display attached to any of the monitor outputs being on to select toe content. For radio functionality, the unit can only work with Rhapsody or Shoutcast Internet radio services.

This network connectivity is made feasible by the receiver having an Ethernet connection. This means that it can work also with HomePlug AV powerline networks when you use a HomePlug AV-Ethernet bridge; and is my preferred “no-new-wires” network-connection method for connecting home-theatre and hi-fi equipment to a home network.

When you navigate a DLNA media server, you have to choose the kind of content you are after – music, pictures or video. If you browse around the same server for content outside the class you selected, this receiver will not start any of that content.

It could be feasible to select audio content by using the receiver’s built-in display and through the use of either the remote control or controls on the unit’s front panel. For Internet-radio functionality, it could be feasible to select Internet-radio content from vTuner, RadioTime or Reciva directories which include access to local radio from other countries.

Sound quality

The sound quality is as you would expect for high-end Sony gear, where it is not coloured. I even noticed this with my computer’s sound which was fed through the SACD/CD input and out through the Preamp outputs to the SRS-DB500 speaker set. I switched the unit in to regular 2-channel mode, then to “analogue direct” to assess whether the digital circuitry was colouring the sound. The receiver and the active speakers were set to “tone-flat” – bass and treble at centre positions in order to really assess how it sounded and I had played one of the early “Café Del Mar” recordings from my PC.

The reason I use this kind of recording is to assess the equipment from a mature user’s viewpoint and find out how it handles music other than aggressively-amplified pop music. In the context of the home theatre, it would also include being able to yield the whole soundtrack of a movie or TV series.

I haven’t been able to test the receiver with regular passive speakers but the power amplifiers are something worth trying out and using.

Limitations and Points of Improvement

I had mentioned that there could be some points of improvement as far as network operation goes. These include the ability to use the unit’s display and controls to select and control audio material from DLNA servers on the home network, without the need to switch on the TV display. Similarly, the receiver could offer what competing home-theatre receivers offer where you can “tune in to” Internet-radio stations offered by vTuner, Reciva or RadioTime directories.

For operation, a main point of improvement would be to allocate one video monitor as a “control monitor” while the other monitor shows video content. Here, it could allow for a smaller screen to be used for this purpose while the larger screen is used for the primary video.

Conclusion and Placement notes

Save for certain network-media limitations, this receiver would be considered as a worthy candidate for a primary “hub unit” for the main home-theatre area. It is also well-placed for audio enthusiasts or people who have material on legacy formats like vinyl records and want to be able to play these material on good equipment.

Notes:

The cited output power is based on manufacturers’ specifications with an 8-ohm speaker load and 0.09% total harmonic distortion (minimum quoted in the specifications).

My comments

This gadget had intrigued me not just because it was a WDS-compliant Wi-Fi network repeater for all of the Wi-Fi networks but was a DLNA-compliant media player without a control surface.

It plugs in to an AC outlet in a similar manner to a HomePlug wireless access point like a Netcomm NP290W, Solwise ‘85PEW or Devolo dLAN Wireless unit. But this connection only exists to power the unit and, at the moment, is available only to fit the Continental-European power outlet.

The main strength in my opinion is its prowess as a network music player for the DLNA Home Media Network. It can be controlled by Windows Media Player 12, recent Nokia phones, TwonkyMedia Manager, an iPhone running PlugPlayer; and other UPnP AV Control Points or through its Web user interface. That same Web user interface can be used to select between six different Internet-radio streams of your choice but you would have to know the URLs of these streams.

You can connect it directly to a music system via its line input or digital input or enable a built-in “flea-power” FM transmitter to have it play through an FM radio tuned to a frequency that you nominate through the Web interface.

The closest competition to this device would be the Apple Airport Express which works as a USB print server, wireless-only router or network music player that only works with iTunes.

What I would like to see for this device would be to have it able to work beyond Continental Europe i.e. available with plugs to suit North America, UK, Australia and other markets. If extra value were to be applied to this device. It could also be improved with HomePlug AV and Ethernet connectivity in a similar manner to the aforementioned HomePlug wireless access points and work properly in an extended service set with client roaming to latest specifications.

The Internet-radio functionality could be improved by having the FritzWLAN Repeater work with an established Internet-radio directory like vTuner, Reciva or RadioTime to select the radio streams. This could then be taken further with access to the user favourites functions that the directories have.

The main take from this is that AVM have pushed the boundaries by adding a standards-based media player to a Wi-Fi network repeater instead of following the crowd.

I have been observing the situation with UPnP AV / DLNA as a standard for network-based music distribution and have noticed something which may be considered unusual in the world of “serious hi-fi”.  A few boutique hi-fi manufacturers, Arcam, Linn, Naim, T+A and Revox, have spent a lot of time in technical research in to achieving the best sound with good music provided via FM radio, records, tapes and CD, have taken their expertise towards music distributed via the home network.

Their solutions have been based around the UPnP AV / DLNA media-delivery protocol over common IP networks and using common codecs like MP3, FLAC, AAC and, in some cases Ogg Vorbis and WMA. Because they don’t need to develop client and server software and that the DLNA media server is available in standalone devices like NAS boxes, therefore, it has become easier for the manufacturers to concentrate on high-quality decoding, digital-analogue conversion and reproduction of the music through their equipment. A lot of these units support the DLNA standard to full expectations such as support for “three-box” operation as mentioned in this feature article.

Some manufacturers have built the functionality in to a receiver(Arcam FMJ AVR600) or music system supplied with or without speakers (Naim Uniti, T+A Caruso, T+A Music Player) or have supplied it as a component (Linn Akurate, Klimax or Majik DS) or retrofit kit for existing equipment (Revox Module Multimedia for M10 or M51 receiver).

Other manufacturers in this league haven’t yet supported UPnP AV / DLNA because of investment in a multi-room audio distribution system or network audio technology they have invested in; haven’t yet developed such equipment or simply that they want to stay away from the field of network audio.

I have written up an article about integrating classical music in to your network music collection and have made suggestions regarding optimum codec setups for your digital-audio files. This is worth reading if you intend to use any of these products with your home network and want to get the best value out of them.

Very often, DLNA and UPnP AV are typically marketed as being for use in the home due to the reduced amount of configuration needed for devices that comply to these standards. But devices based on these standards can appeal to business use, especially to small “mum and dad” shops, community / religious organisations and other similar businesses who don’t have regular access to “big business” IT resources.

The functionality is typically available as low-cost or free software or, in some cases like Windows XP and Vista, available as part of the operating system. There are some “business-grade” network-attached storage boxes that have the functionality for business continuity as well as the ability to work as DLNA-compliant media servers. A good example of this are the Netgear ReadyNAS units and the QNAP units, including the TS-459U Series 4-disk rackmount “pizza-box” NAS server which would be pitched at the office server room.

The main issue that one will have with this kind of setup will be that the network that you intend to connect the equipment on must be on the same subnet or logical network, served by the same DHCP server. This will be fine for most small-business, and SOHO networks, including the “private” segment of networks that provide Internet access to the public such as wireless hotspots and Internet cafes.

If you are concerned about security of business data or the integrity of business systems, you could run a separate server for the DLNA-presented media data rather than use the main server for this purpose. Then you can lock down the main server as tightly as it should be for the data.

Visual Merchandising

DLNA-based setups can come in to their own when it comes to all sorts of visual merchandising applications. This is more so for small businesses who cannot afford to buy business-grade “digital signage” or find the “digital signage” difficult to manage due to complex setup requirements.

You can have images or videos of products that are always kept fresh and up-to-date and can intermingle these images and videos with up-to-date “electronic signage” that you create with programs like Microsoft PowerPoint. The best example of this being used would be the real-estate agent who uses the setup to show pictures of the houses he has currently for sale or a beauty salon showing examples of the most fashionable hairstyles they have done lately.

A DLNA-compliant network electronic picture frame like the Kodak EX1011 or the D-Link DSM-210 can work wonders here as can any DLNA-compliant network media receiver (or games console) hooked up to a large flat-screen TV or monitor. Similarly, a DLNA-compliant flat-screen TV like one of Sony’s recent LCD TVs can fulfil the same needs here, especially now that the cost of these sets in in affordable territory and the sets are available from most electrical retailers.

The media server can be part of the file server’s functions or can be hosted on a separate box such as a network-attached storage unit. You just need to add the media to this server by using a standard network file-transfer protocol like SMB or FTP.

You will need to make sure that the media server presents the files either by keywords (tags) and / or folders of the file system so that you can file the pictures how you want to file them. Windows Media Player and TwonkyMedia do support working by keywords and folders.

If you use a presentation program like Microsoft PowerPoint to create “electronic signage”, you just need to export all of the slides in your presentation as JPEG files in to a folder available to the media server. This is done in PowerPoint by opening the presentation and selecting “File” – “Save As” and selecting “JPEG” as the file type. You then have the option of exporting the current slide as a JPEG or exporting all the slides in the presentation as JPEG files in a folder named after the title of the presentation.

Background Music

If you are sick and tired of the radio or those business-to-business music services, you can use a computer as a music server, with the music playing out through a DLNA-compliant network media player such as one of those Internet radios.

As I have mentioned in my previous DLNA feature articles, it is very easy to do whether you decide to use a computer or a network-attached storage box as a media server. Most of the network-enabled music players support shuffle-play which can be very useful for this application and a lot of them have a line-out connection so you can connect them to a public-address amplifier or music-on-hold interface.

Education – The media library

A DLNA-based media system can work well when it comes to education. It doesn’t matter whether the idea is to show a video to a class or whether a student is viewing a video they saw in class “once more” in the library.

A capable DLNA media server with a properly-indexed media collection can work wonders here, with the users selecting the AV material through the DLNA media player’s user interface. Most such players can connect to existing AV equipment or the DLNA functionality can be part of the equipment’s functionality.

Similarly, if the media server provides it, you could allow Web-based access via any computer connected to the facility’s network. This can allow wireless-linked computers to be used to “pull up” the learning resources.

Other business-based DLNA applications

DLNA is eventually heading in the direction of a common IP-hosted data system for transferring media between portable and fixed devices. A typical application may include uploading images and movies from a digital camera or camcorder to a “base” computer for editing and viewing. Similarly, there may be the application of downloading AV material from a computer to a smartphone so it can be viewed on that phone’s display.

Conclusion

What needs to happen is that DLNA needs to be viewed as not just being for the home but being for business and educational life as well.

My Comments:

Previously, I had made some comments about the NETGEAR Digital Entertainer Elite network media receiver / server that was previewed last year. I had mentioned about Netgear considering the possibility of extending its functionality as a DLNA media server, especially since it has a user-replaceable 500G SATA hard disk built in.  The original model that was talked up happened to be the EVA-9000 but this model that is now released is the EVA-9150, but this unit is part of the same series.

Now it is released worldwide rather than being “dribbled out” in to different countries over the year. It is selling for a manufacturer’s retail price of USD$399 which may mean a likely street price of USD$300-350. This may make the unit more suitable for people who have invested in good-quality flat-screen installations.

It would also come off as being useful in the “small-business” context for “digital signage” and similar applications, whether you upload the pictures to the hard drive or hook the unit up to a computer or NAS running a suitable DLNA server. Here, a “showcase” of regularly-used material can be kept on the hard disk, but other material can be held on computers that are on the business network.

I am certain expecting that this could bring Netgear further in to the network media receiver market and will make this market competitive.

My comments

Now Netgear is raising the bar as far as these network media receivers is concerned. It is an attempt to provide a UPnP-complint high-end network media receiver for those of us who want to bring the video files held on the NAS unit to the home theatre that has the big plasma screen and surround-sound.

The built-in hard disk option could be improved upon in the form of being able to be a UPnP AV / DLNA media server. This can then lead to the unit being an entry-point media server or supporting the provision of “load ‘n’ show” media being available on other DLNA media devices in the home network. This is if the purpose of the optional hard disk isn’t just for downloading content as part of an rental-based or subscription video-on-demand service. Another ideal function would be to be under the control of another UPnP AV control point, whih can allow it to play audio content without the user needing to have the TV on to choose the content.

It will be interesting to see what the reviews in the computer press and the blogosphere think of this unit and its usability.
