I have not head any Class D amp so far in my own experience sound warm or syrupy - I would consider that sound from tube McIntosh as warm and syrupy but that is my opinion and my own personal experience.
If I was looking for a Class D amp I would contact Tommy O'Brien with Cherry Amps and get something he offers with a trial period. I just heard the tiny mono blocks he manufacturers (125wpc) on Klipschorns (highly modified) speakers and they were open, with nice details and sweet sounding. No they did not sound like the 1 watt 45 tube amp or the pure Class A 30wpc mono blocks but not bad overall. Very listenable.
Happy Listening.
