@caphill - hopefully you are still monitoring this thread. I tested the AV8805 in my system using the beginning part of a movie that had excellent music in the intro and very high quality audio and video. And yes, it did have excellent surround elements in the beginning of the movie. We did not do an Audessey calibration - it was completely turned off.

Regarding a second topic, I have tried room correction and I do not like that at all. I had the opportunity to do a Dirac room correction in my own theater and I could never get it to sound right. Dirac is so horrendessly intrusive on changing and tweaking the sound that it creates problems in my opinion. The Dirac processing did weird things to the phasing of the sound and made all sounds seem like they were in your head (like listening to headphones) instead of way out in front of you like the movie ambience is supposed to be. I could dial this down, but it never sounded good. It also tweaked the frequency response and sometimes seemed to make things too smooth - I lost resolution and microdetail in the sound/tones/textures. Also, if aggressively used in bass, it caused subwoofers to peak and push to much at bass null frequencies. Sorry, but Dirac is not for me.

I think I tried YPAO Yamaha auto-correction. That did not work well either. In both cases, things just sounded better and more natural with any sort of automatic room correction turned off. I do a lot of room acoustic treatments and I use careful equipment matching and fuses to control timber and response of the equipment. That works significantly better than any sort of room correction.

Actually, at RMAF there was a room that really touted "room correction". I listened for just a bit, and it sounded nice and balanced, but I could not understand what the big deal was, lol. Many other rooms sounded nice and balanced. This "room correction" room actually sounded rather flat and sterile, most likely because it was using an external/outboard room correction device and signal goes through A/D and D/A stages - which lose all the voicing and "singing" of the preamp/processor.
