Asx's feedback is different from the norm, but I commend him for putting in the time to swap out equipment to find the best unit for his needs. I keep trying to think of what variable in the 990 equation might be off to produce the disappointing performance that he's reporting, because it does seem unusual. So far I haven't seen anything obvious. Odd bass management settings can easily yield very disappointing results, but Asx clearly has a good handle on how to set up a surround processor and should therefore not be doing anything so severely out of whack. I wish I could suggest something that would yield the very pleasing performance that I'm getting from my 990...
