High end Class D amps?

@noble100 Hi Tim---thanks for the info. I don't consider myself a new audiophile per se, but in the past, I didn't really pay much attention to specs like I do now. I was a young 20-something back then and just bought what sounded good. As I've gotten older, I've become more interested in what matches better with what and I'm trying to learn from all you guys. So now I have a Luxman 505UXii integrated with a pair of Dynaudio S40s as well as  pair of Tekton Lore References. I alternate b/w the Dyns and the Lores depending on my mood and musical tastes. I love the Luxman but I at times I wish it had some more punch or something. I caught a video on YT recently that had a new Luxman connected to a Pass amp (I think)---I can't seem to find it now. Anyway, it got me thinking about higher output class Ds (like 200+ wpc) and wondered how that would go. I really appreciate everyone's input and suggestions. 

The Japanese company Spec design very well regarded Class D amps that are apparently very valve-like in tone, though they are not the mega-watt things that a lot of people seem to use Class D for.

I have 300W Class D amps in each of my semi-active speakers and they work brilliantly at driving bass.  But the passive end of the speakers I prefer driving with Class A.. It is the perfect combination.

Another vote for Bel Canto.
I'm using the Reference 600 monoblocks as a stopgap to drive my Focal Stella Utopias while i save for Boulder 2160. The fun doesn't stop, i can't believe how well they perform

What an interesting thread. Is anyone using subs that have high impedance inputs, like RELs, with class D amps? Do you notice any difference in the performance of the subs, or an impact on the performance of the full range speakers?

I always thought pure class A amplification was most ideal.  So why manufacture Class D amps?  I think Class D amps push and pull the speakers, not sure.  I like the ARCAM AVR 850 because it produces pure Class A amplification the first 50 amps.  Really sounds great.
