I have a 10+ year old AVR that still works wonderfully. The only reason that I want to upgrade is to get HDMI and support for the lossless formats. Audyssey and DTS NEO:X will be nice pluses, but that is all, they are just plusses. The biggest upgrade I plan to do honestly is move to separate amps. I think that will give me more bang for the buck than anything else honestly,. I plan to get a 5 channel Emotiva XPA-5 for my Fronts and Center (5 channel in case I add wides) and a 7 channel Emotiva UPA-700 for my Front High, Surround and Surround Back channels. Then I will just upgrade my pre pro when necessary to add formats, as in a room my size (16' X 19') I honestly cannot see going beyond 9 speakers, much less the 11 that I will have amp power for.
