Hi Ortho
Just to chime in as a fellow 3311 owner, I had an identical problem after running Audyssey. As others mention, the issue was specific to music played in multi channel stereo. I don't think I ever fixed the problem in that mode. Instead, I just started using PLIIx music. After that, I slightly adjusted the Audyssey volume assignments, but not very much. For the PLIIx music setting, I set center width to 7, in order to avoid using the center channel for music. I set dimension to 4 and panorama off. Not sure how this will work in your room, but now I really, really like how the 3311 integrates. These settings seem to provide an enveloping sound that I like, while primarily placing the M80s on center stage. I'm using M80s for my mains, QS4s for surrounds, and M3s for rears. I also found that dynamic EQ added a great deal of warmth to my music.
Anyway, hope this helps.
Brian
