I don't think I've even mentioned the word "Audyssey" or "DEQ" in this thread yet.
So I guess I can do it now.
Even if I were a billionaire, I would not buy anything without Audyssey XT32 Dynamic EQ (DEQ). I use Audyssey Bypass L/R + DEQ for EVERYTHING. It is my preference. I've tried Dolby Volume Leveler (which is supposed to be equivalent to DEQ), but the bass didn't sound as punchy and dynamic to me as Audyssey DEQ.
Maybe if DTS were to come out with their version of DTS-DEQ (or something like that), I may love it because I usually prefer anything-DTS over anything-Dolby.
