New Class D amplifiers

Hello. I'm very interested in getting your opinion on the newer Class D amplifiers.  There has been a couple of very positive reviews (by Guttenberg) of the Bel Canto C6i and NAD M23.  These, and perhaps some others are offering new technology that significantly lower the class D noise level and other drawbacks.    

I currently use a Class A amp, Pass Labs INT-25 (with Dynaudio Heritage Special speakers) which has a wonderful sound. But I am transitioning to another location, and due to using Roon primarily I find that this system stays on most of the day.  Due to heat and power usage of Class A amplifiers, I'm interested in translating to Class D if I find something comparable.

I’m a tube head and never warmed to many Class D amps. But, as time went on and I heard more Class D offerings that and began to find them sonically appealing.

About a year ago, I bought a "summer amp" to substitute in for my tube amps during the heat of the summer. I tried a Ken Ishiwata voiced Marantz reference Ruby integrated. It sounds as good as several of my tube amps, and better than a few well known names. It doesn’t beat my 48 watt SET 805 Class A amp, but it’s really, really, good. I hate to list the tube amps that the Marantz beat in my system.

I think the key to Class D is voicing by the designer. I’ve tried several other Class D amps that sounded a bit too dry and lacked warmth and life.
