I have recently faced the same issue and was considering the Denon 4306 or the 2807 but decided the best thing to do is hold off for now.
From my research it is my understanding that with the HD DVD format coming down the pipe, there is also HD audio to go with it. The HDMI switching receivers out right now are all HDMI 1.0, and to take advantage of the new audio formats that will be associated with HD audio you will need a receiver that can handle HDMI 1.3 cables...at least that is how I understand it. Neither the 4306 nor the 2807 can decode these new formats.
Here's what Cnet had to say...
http://reviews.cnet.com/Denon_AVR_4306/4505-6466_7-31736750.html?tag=lst "...the receiver lacks the ability to decode the new Dolby Digital Plus/TruHD and DTS-HD soundtracks found on forthcoming HD-DVD and Blu-ray discs. But let's put that into perspective: no receiver currently on the market can handle those formats, and it's unclear what the advantage would be if they did. Dolby, DTS, and the hardware manufacturers are telling us that HD-DVD and Blu-ray players handle the soundtrack decoding internally and pass the discrete audio streams onto the receiver via HDMI or the 5.1 analog inputs--
obviating, it would seem, the need for next-gen internal surround decoding."
(emphasis mine)
I want my next receiver to last a long time, and with these new formats just around the corner I think it is best to wait a bit.
Can anyone else provide more input in this regard?
