I've got a 950/755 + old 2 channel running the rear surrounds. Couldn't be happier for home theater. I bought a sears relay (in the power tools section) to switch the old amp. The 755 is quiet and dynamic. I have an entirely separate high end system for music- so comparisons are not fair in that department. I did swap the 950 with my ARC SP9 for kicks. Of course the tube unit sounded better but not by an enormous margin IMHO.
