Sony has given What Hi-Fi? Sound and Vision an exclusive briefing on its entire 2008 AV receiver range, with tech specs and prices

Following an exclusive, and extensive, product briefing from Sony here at What Hi-Fi? Sound and Vision, we can now lavish you with more information on Sony's 2008 range of receivers and hopefully sort out any model confusion in the process.

There are five models in the new line-up, and in a nutshell the UK will be receiving:

STR-DG520 - £180 - available end of JulySTR-DG820 - £300 - available end of July

STR-DA2400ES - £500 - available AugustSTR-DA3400ES - £700 - available AugustSTR-DA5400ES - £1500 - available August

More after the break

Sony's representatives were kind enough to drop off a review sample of the STR-DG820, which is now warming up in our listening rooms. So visitors to whathifi.com will be able to read our exclusive online review next week.

As we mentioned in an earlier news story, the STR-DG820 is a 7.1 channel receiver boasting 100w per channel. It's armed with four HDMI inputs and one output. It also supports all HD audio formats, Dolby Digital Plus, Dolby TrueHD and DTS-HD Master Audio. And, after our briefing, we can also reveal:

All the new receivers have been built from scratch with brand new components - even the solder used in the circuitboards has been changed.

Extra effort has been made to reduce the effects of internal vibrations on the new chassis.

The STR-DG820 features 1080p/24fps passthrough, but no video upscaling or upconversion (contrary to the information we were originally told by Sony). The receiver also supports Deep Colour and x.v.Colour technology.

The remote control is similar in look and feel to that of the W series LCD TVs.

An on-screen display is provided, but there's no display output to your TV or projector.

The entry-level STR-DG520 has very basic specification (not surprising, given its highly-affordable price) and some of the main differences between it and the STR-DG820 are:

No A+B speaker selectionNo AV input on the frontTwo HDMI inputs as opposed to four on the STR-DG820No HD audio decoding or LPCM via HDMINo Dolby Digital EX, DTS-ES, DTS 96/24 decoding, just standard Dolby Digital and DTSNo Deep Colour x.vColour compatibility

We're just waiting for the specification of the ES models to come through, but as soon as we have them to hand we'll get the information posted on the website.

One last thing. Sony dropped off another piece of kit that we're sure you'll be interested in. But can you guess what it is? We'll be divulging top-secret information on this product on August 1st. So, be sure to check the website for another What Hi-Fi? Sound and Vision exclusive.

UPDATE – Well, we've been going through the specifications of Sony's new ES receivers with a fine-toothed comb and we've finally compiled a list of the main specs for each of the new models.

Strangely there's no mention of multichannel analogue inputs, but we'd surprised if the new models didn't at least offer 5.1 analogue inputs.

Needless to say, we can't wait to get our hands on them. In the meantime, stay tuned for an in-depth review of the £300 STR-DG820. We'll post it online in the next couple of days.STR-DA5400ES £1500
