One of the best amps on the market, although it's a true FDA (full digital driven PWM), so not "exactly" a "class D" (which is analog driven PWM) :

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.
