Since you're looking at purchasing next spring or so, as am I, FYI Denon has a mid-level pre-pro in the works that may be slated for release next year. They had one based around the 4310 but I don't think they thought it was marketable enough, put it on hold, and I think the new one may be more based around the 4810/5308. The model was AVP-CIX and hopefully there is news during CES.
Yo, Rat, will you please keep me updated with any news, even via PM? I know strube was talking about this too, at one point. I am afraid of what it's going to cost, but I am interested.
My good friend's all-in-one bdp/amp just died. I'm thinking of starting a trickle down upgrade effect.

Denon for me, sell 805 to brother, and the older HTIB-Onkyo-receiver sold to friend.
Well, come to think of it, I bet I'm going to balk at the price.

And my bro's TV stand doesn't have enough height for the 805.

He really does want mch audio via HDMI though, for a couple of reasons. Hmmm . . .
