rodm_2001: I don't have any experience with these amps, other than hearing them briefly at shows or stores, and not with Ohms. The only Class D amp I have used with my 2000s was the Arion Audio RS-500. I liked them a lot, but it was a loaner pair and I was not amp shopping. I use an Odyssey Audio HT3 (with cap upgrade) for my 2000s, and I love the combo. But, this is with a pair of powered subwoofers, so the power demands of the 2000s is not as high as if they were run full range.
Mapman uses bel canto Class D amps, and he seems to really like the combo with his Ohm 5s.
But, I would hold off on the amp purchase. Try the Ohms with your receiver first, for at aleast a couple of weeks. Then, if you think they are somewhat broken in and you still want more, try to get a more powerful amp that you can return, or borrow one from someone. FWIW, I briefly hooked up my 2000s, without the subs, to an 80 watt per channel Onkyo receiver and was surprised by how little was lost when I went to the lower power and left out the subs.
