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 have AGD Audions and Atma-Sphere Class D.

Both are excellent. Among the best ever.

The AGD are more tube-like and the Atmas are more dynamic and transparent.

It is a difficult choice between the AGD Audions and the Atma Ds.

I may keep both.

Speaking generally, they are greatly characterized by the nationality of their designers. Alberto, being from Italy, has created amps that, very much, have a romantic, organic bent. The tube like output stage of the Audions is more than a way to easily upgrade. But a tribute to SETs which also inspires the sound.

The Audions are beautifully and lovely to listen to. Easy on the ears. Delicious detail. Terrific sound staging and imaging. And mellifluous.

The Atmas are American meat and potatoes. More meat on the bones. More detail. And tremendous bass. They are also more dynamic. They sound like Ralph’s tube amps with more clarity and bass.

I use an Atma MP-1 preamp and there is clearly synergy. This may ultimately inform my decision on which to keep.
