Interesting, especially if you played the stereo Grand Piano in 'solo' exposed mode (no auto accompaniment). Hmmm. I suppose Donny should have kept his PAS system then?! For whatever reason, when I last audtioned the PAS with it's 'new' EQ settings, going out Tyros Left and RT channels separately, as well as into the 2 separate channels on the Bose PAS, I still heard serious 'stereo phase cancellation' sound degradation. I've wanted to upgrade my existing PA system to a Bose PAS for quite some time, but until I'm convinced that the stereo phase cancellation problem has really been resolved with the Tyros2 + PAS system, I'm sticking with my current EV SxA100 active PA speaker setup until I upgrade to the awesome sounding EV SxA360's. - Scott
