I'd recommend you consider the active ATC's and the all-
sonic(speaker + poweramp) solution this represents, compared
to the McIntosh MC275's + B&W's or passive ATC's.
Active ATC's to my ears make for a very worthwhile sonic
advantage compared to their passive siblings, even where
extremely capable amp constellations are in use. Whatever
sonic "flavor" you're after I'd seek outside the
influence of the (separate) poweramp, especially in light of
the inherent advantages that springs from the active ATC's.
