"The following Denon models can receive 7.1 PCM over HDMI and apply digital signal processing incl. EQ in the receiver:
AVC-A1XVA, AVC-A11XVA, AVR-4306, AVR-3806, AVR-2807, AVR-2307
This would mean that all those models are at least "Level 5 Receiver" (or even level 6?) accoding to my little understanding (Lindahl already mentioned the 2807 under "Level 5" if I remember correctly).
Using the information you provided and doing a little bit of extra reasearch, it looks like all latest HDMI Denons are level 6 (accept 7.1 PCM and do processing). I've updated the first post to reflect this. Thanks for the info!
So there ARE receivers at the moment that can decode DD+ and DD HD (lossless) or an I missing something?
As Sanjay said, no current receivers can do this, you need a receiver that has HDMI 1.3. But the great thing is, you don't need this type of receiver! The high-def DVD players can decode the signals for you and send them as multichannel PCM signals either over an analog connection, or, preferrably, over HDMI 1.1.
This is actually preferrable since special decoding can be done on the player, for example director comments overlaid on the original soundtrack. These types of special decoding can't be done on the receiver since it doesn't have access to the necessary information on the disc.
Believe it or not, providing the new DD and DTS formats over HDMI 1.3 is actually a step backwards and will only cause more confusion and problems. I really don't have a clue what they were thinking.
EDIT (added): They should have spec'd all HDMI versions to only
carry uncompressed lossless audio (PCM) at various resolutions (24/192, etc.) from the very beginning, like they did with video. It was extremely boneheaded of the HDMI consortium to do what they did with multiple audio formats. They only thing they did was give receiver manufacturers opportunities to screw things up. Not only that, but if we move to HDMI only receivers, you won't need all those Dolby and DTS encoders anymore, making them a whole lot cheaper. All you'd have would be a PCM processor.
I now have a Denon A1-SRA with a 7.1 input. Has this something to do with this and can I use it in the future?
I'm not familiar with the Denon A1-SRA, but you can certainly connect 7.1 analog outputs to your 7.1 analog inputs to achieve nearly the same thing (obviously, there's a DAC involved, and possibly an ADC involved too). If it has an HDMI input, it may
be able to receive 7.1 over HDMI (or 5.1).
