As a matter of fact, I've got Paradigm Reference Studio/60v2 mains, Studio/CCv2 center, and Studio/ADPv2 rear surrounds (side surrounds are Axiom M3ti's due to side wall speaker mounting challenges) all driven by a Model 990 feeding a pair of M200's for the mains and a Model 750 for the center and all four surrounds. I've been very pleased with the overall system.

For what it's worth, my wife and I listened to a co-worker's Rotel 1068/1075 setup driving B&W's and found that system harsh in comparison to ours (enough so that as soon as we got in the car, she commented on how much more she liked our setup). At the time, we had a Model 950 processor - the 990 is a nice sonic improvement over the 950, so I would expect the contrast between the two systems to be even more noticeable now.
