Rotel class D amps. Buy or not?

I listened to my Studio 40's hooked up to a Rotel at the dealer when I first started looking at speakers and I didn't really care for the sound. In fact, I left there and went and auditioned some B&W's. I went back to the first place a week later to listen again and really liked what I heard. I asked the dealer if anything was different from the week before and he told me they just got some new B&K amps in, and that the Paradigms were hooked up to them. I now have the Studio 40's and a B&K 200.2amp.
