I recently bought a Audiophonics HPA-S400ET Sparkos Edition, Class D, Purifi, 2 x 400 watts @ 4 ohms / 2 x 200 watts @ 8 ohms amplifier. I am very happy with it. Take a look at the reviews on Audio Science Review.

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.
