The professional A/V people that I know and work with (ones who do commercial, churches, etc.) don't recommend pro amps for 2-channel or HT use, and don't use them in their own home systems. QSC, Crown, etc. is great gear, but pro equipment is made to be rugged and reliable, not to provide a very high level of sound quality. Very few commercial installations are designed to, or have the ability to, provide the kind of sound quality that we want in our homes, regardless of the electronics - too much ambient noise, questionable room acoustics, highly distributed seating/listening areas, etc. Good gear, just optimized for different use than our home gear is.
