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 selection
No AV input on the front
Two HDMI inputs as opposed to four on the STR-DG820
No HD audio decoding or LPCM via HDMI
No Dolby Digital EX, DTS-ES, DTS 96/24 decoding, just standard Dolby Digital and DTS
No 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.
