Your friendly neighborhood Digital Amp Company shill here-
Bemo, have you ever heard one of DAC's Class D amps (the Cherry series)?
Not Ice or UcD, but much better than the examples of those amps I've owned (Channel Island UcD) or borrowed (Rotel ~100 watter ICE).
I see you are in NYC? Maybe we'll hook up at a GTG someday and you can hear the Cherry. Or better yet make it to a Rave (maybe you have? I don't know everyone's handle)
I'm not saying it'll be the amp for you, and while I wouldn't call it particularly cool it certainly is not lush and won't add any lushness to a system. We heard it on already icy-cold, sterile VMPSs and it was not a good match. But on my Von Schweikerts the Cherry more than impressed the Ravers for a solid 8+ hours.
So in the right system I think some of the Class Ds can be a good choice, all things considered.
