So glad I found this post. I'm going to try to reactivate this discussion because I'm facing the same decision (876 or 2809?). I've been all over the net reading reviews of these two as well as the Marantz 6003 and 7002, Yamahas and Pioneers, but I'm pretty sure it's down to these two.
Now, I'll be the first to adimt I'm entry-level in terms of my gear. I play my PS3 thru my 46"XBR5 (calibrated of course), listen to a lot of live audience recordings (yep, Phish/Deadhead bootleg collector here), have a 500GB Buffalo network drive for which the PS3 loves to display everything out of order (a post for another time) and I just bought Cambridge Soundworks' MC305 system with the dipole/bipole speakers (yeah yeah, CS is supposedly a sin from what I've recently read, but it was 40% off so I couldn't resist...doesn't seem that bad so far though).
So here's the thing, that's about all I need to do with a new receiver, but I LOVE new toys with bells and whistles and want to at least attempt some future-proofing and get the best wrap-around sound field and clarity...and perhaps some processing that makes the bootlegs shine and doesn't crap all over a good video signal. I read specs and can't help but want the toy with the longer list, but I also recognize I could be just going overboard. What would you recommend? Are the 876 and 2809 excessive in terms of what I'd really need? Can I go with the 806 or perhaps the Marantz 7002 (altho it only does 720p, so do I just fiber optic the PS3 audio to the receiver and hard-wire HDMI video to the XBR5)? THX Cert sounds dandy but do I really need it? Am I going to find myself grinning ear to ear with just the 706? I almost feel like reading all the reviews only confused things more and added questions. Please help...I learn fast, but I'm on overload.
