Hi Scott,
I followed a link posted on S-Z over to the Bose forum and found this comment on stereo sampled sound:

I don't care much about this person's critique on stereo sampled sound, but his comment on what your audience actually hear. Would your audience hear the difference sitting in the listening area?

I took my PAS to the extreme yesterday by playing my music for the church choir. They had 4 condenser mounted high above the singer, plus two Sennheiser handheld for solos, all mics went in my mixer with my two keyboards and send the mixer's L/R outs to ch1 and ch2 of the PAS. We had a little trouble at first because of the sensitive condenser mics, and ended up had the PAS about 8 feet directly to the right of the choir. Things went great from there. It was pretty amazing that what the choir heard was what the congregation heard!

Uncle Dave was absolutely right when he talked about the comments he received from his audience. In my case, it was the same.
