Even if you let his considerable network skills aside, Sony’s shines 3000 euro receiver still with significant pounds. Or depending with modesty. So allows DA 6400 ES the STR though, to make the Setup from the finely drawn, film transparent graphics – screen menu as well as on the device display. The fan, including a corresponding optional dock via digital management input (DMPort), open but, that he needs the monitor then the comfortable operation of its iPods.

Ambitious filmmakers not exactly spoiled the new Sony. He is enough the video data advancing to the six HDMI inputs when needed on the gentle way – without menu admission – to the two alternative selectable 1:1 HDMI outputs. On a video equalizing, as current large Onkyo’s offer, there is work to do without.

This is true even if the Siebenkanaler (where Sony was not S-video connectors) converts analog easy-CVBS or 3 component video to HDMI format. Naturally he is capable of full but then taking painstaking movement of the sequence of pictures with half number of lines to produce (de-interlacing of i to p). Of course he converts cheapest also the line number up up to 1080 p (p for frames) on the respective monitor.

As a real wealth of 6400 ES brings the STR since now not only a fine reputation great video processor Faradjou/Genesis, but two. And that extra for a user in a secondary room via the 3 components line to be able to receive his own, highly-converted to 720 p or 1080i image in addition to its own menu.

That the Sony (as well as even the smaller STR DA 5400 ES book 11/08) the one and can picture in picture (PIP) to represent the other film, comes as a significant niceness. As well, that he after connecting a camera to the socket “external video” allows for example a PIP-baby monitoring.

Only in addition to Yamaha’s DSP Z 7 (3/09), the Sony amongst other things offers a party mode, which ensures that the music signals from a source without time offset come to the power amplifiers and high level outputs for region 1, 2 and 3 and that it sounds there then and there the same distinction.

As absolutely new and exclusive Sony may call the “quick click” feature of its new flagship. Because it often degenerates into a plague, with a number of remote clients physically having to handle, such calls as 6400 ES the STR now virtually via screen on the plan. It takes but first much brain wax and patience, to fill the electronic memory in the remote control (a code table or even learning infrared commands need to help) with the corresponding knowledge. But central control of an entire home theater system including a lighting system from Lutron may go resin hardened welding actually more elegant by the hand.

Previously have only a supplied with (more is there as an option) and installed by the receiver-driven IR emitters, that he sees in the IR Eye of AV-combatants.

The Sony of course controls in-house sound suppliers in the ordinary remote network. In the case of the high end because he is capable of 6400 ES (test shortly) via the HDMI cable clock pulses to report back SACD/CD player STR, so that the player haarscharf based on the work of the D/A converter in the receiver, and so that time error can avoid talk of jitter.

If you like, finally may rely on an automatic calibration system; in the sound-optimised stereoplay listening room, the Sony but joined with advantage in manual boxes Setup and otherwise as natural flat positions. About against his similar in terms of appearance and equipment small brother STR DA 5400 ES.

This however soon retreated with some bruises, because alone against the incredibly plastic and through muscular, confidently moving through bass of the 6400 he didn’t – not in stereo and not surround only. Natural, warmer and more beautiful ramification in MIDs and highs, showed his top-class large. And only the very top in the listening area they had one thing in common, because Sony raised her to the gentleness: for metallic dangerous Percussions fire, both receivers took a discreet cautious attitude.

Brought more light on the events and on the bass with almost the same emphasis to a tick had a stringent, Rotel of fabulous RSX 1550 (2/09) was rather against the new Sony. This offered more depth and atmosphere however the CD passages – such as the sonic landscapes of Kari Bremnes ‘Journey’ (Indigo-CD) -, while the voice of the singer appeared even more natural and feminine. With its highly pleasant mild sovereignty, the Sony got 43 stereo points and thus got a counter.

When the outdated surround 6400 there absolute best swung to the STR. Which he seemingly catapulted with light hand in the listening room, rustic grim, completely unfettered E bass growl of Medesky, Martin, and wood’s had “Uninvisible” (DTS sampler) oppose nothing equivalent to the Rotel. And when also the pool less flashed, the drummer on a three-dimensional, still solid in the room posted Hmm raged.

The character of the Sony is almost cheaper impacted on Al di Meolas “One Of These Nights” (in-akustik-DVD in Dolby Digital). He brought the very fine for the format, but also almost over slender sound to an impressive wealth and colored flower, while he appeared via RSX 1550 comparatively spitzer and glassy.

Only in Blu-ray-HD titles managed to repeat the Rotel. He did not “Appalachian spring” with the San Francisco Symphony Orchestra in Dolby True HD with advantage of fresh, violin soul notes, elegant before, while the Beary Sony – yet he remains with majestic severity and spaciousness was impressed – was almost already something to quiet. At exactly the same differences came in the “Figaro”-DTS-HD master recording Deutsche Grammophon no more than a stalemate out. In the sum of all its qualities no doubt but, that Sony’s net go-getting STR as 6400 ES is one of the best in its genre.

Music in the home network to stream, she had to be previously stored in digital form on the PC or NAS server. Then appropriate network player can access and comfortable, as well as in top sound quality play back the sounds.

With the STR as Sony now introduces a new feature for the home networking 6400 ES, which allows you to stream and analog to the receiver connected sources in the network. To do this, the Sony receiver flagship contains a UPnP-AV server as he is responsible for the distribution in the network also on PC or NAS. stereoplay 8500 by TEAC tried out with the network audio player WAP him, just showed the Sony as a server such as the widespread Twonky media server.

The Sony offers all connected analog line level source to food network; easy, it’s about the setting of “Source”, in which the source was just on the receiver is automatically streamed. Digital SPDIF Sony not to stream allows connected devices, however these can be connected in addition analog, to use the new feature.

Namely, after selection of Sony as a server, the network Player displays not only the analog inputs, but also the also streambaren FM tuner including its pre-programmed channels. A caveat is that only a network player on the Sony can be accessed; several rooms can be this way so not with music self-sufficient. It is nice that the analog server in standby mode of the receiver functions.

Except for the server as 6400 ES contains also a client, so a network player feature of STR. Let is play music, photos and videos. The latter was possible only via separate clients.

Regarding the audio formats offers the Sony MP3, AAC and WMA without DRM protection, WAV files but not run up to 48 kilohertz, with 96 kilohertz. The ability to search, a feature that audio/video/photo network players generally do not offer the directories during music playback is very good.

This control structure allows for a slide show with background music, it can thus only selected the music and then start a photo sequence. With regard to this very important for the practice, the Sony is so well prepared.

Sparse, the video section, however, fails because only the formats MPEG2 and WMV in standard resolution run. Although ripped DVDs and recordings of the DVB receiver, high-definition formats of any kind remain but sidelined.

For Web radio reception, Sony has set up access to the programs by Shoutcast which thousands of stations available are right off the bat. This favourite lists can be created directly during playback. Well here are the clear presentation and ease of use.

Speaking of operation. AV receivers in the class of the 6400 is already an extremely feature rich device that is again extended by the network capabilities. There is therefore a clear operating concept – as it offers the Sony – of great importance. Also the great display menus with album art are convincing. The display on the unit could show more but, so the network music playback with the TV works.

The ES supplied utility application software is useful for configuration via PC/network. However there is without them directly with the device/TV – easy network setup-run wizard.

Access to media data runs via UPnP AV server – like Twonky – or using the VAIO software also supplied which allows the playback of streamed via receiver analog sources.
