I've had very good results from Audyssey on my Denon AVR-891 that set up my two M22s that are perched on their own Velo 10" subs, a Sony Center Speaker & two QS4 surrounds. I find that the sound in my oddly shaped room is most satisfying.

Audyssey found that my subs were set at way too high volume levels that I corrected by turning them down by almost in half. Furthermore, it found that the QS4s were indeed 'out of phase' because of my dyslexia in reading wall mount Axiom's instructions, ha!! After these corrections, all is well.

Audyssey works very nicely for both HT & audio in my room. Overall, I really like it...
