Rotel class D amps. Buy or not?

I replaced my ATI 1505 (5x150) with an NHT Power5 (5x200 - ICE) and it runs significantly cooler with no strain in producting monsterous bass from my NHT 2.9's which are very inefficient. It is absolutely quiet with no coloration that I can hear at any point. I'm pretty happy with Class D...and since the NHT is now discontinued, I was able to get an irresistable deal here on Audiogon.

I can't comment on the Rotel....

I have not heard the particular Rotel you mention, but that Parasound is still a great amp, and sounds better than any Rotel I have ever heard.

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.
