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 also recently switched to AGD Audions after years of running an Atman-Sphere S30 Mk3 OTL. I love the sound of the S30 OTL amp but was getting frustrated at valve availability, adjustments and energy consumption.

The AGD Audions have been a terrific addition to my system. They are silent when idle (important as my speakers are 107dB/W) and require no warm-up period. The sound is even more transparent with wonderful imaging extending well beyond the speakers and further back. Instruments are easier to pick out from a complex mix.

The bass is very tuneful with overall a slightly ‘lighter’ feel to it than with the OTL amp. I’m able to tweak this as my speakers (Avantgarde Duo) allow me to adjust bass crossover/gain. I’ve also found that my REL S812 sub seems to go even deeper and ‘faster’.

I’me really impressed and think you’re on the right track with either the AGD Audions or the Atma-Sphere Class D amps.
