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.

@innersound300  Gene of Audioholics is not someone I would rely on for audio advice. He’s a notorious cable denier, who when challenged to back up his claims predictably seeks out the nearest rock to hide under. 

@grantgg I would also look at Orchard Audio and VTV, both designers have made huge strides in implementing GaNFET technology. Both have received glowing reviews.

I have a pair of Atma Sphere mono blocks (Class D) on order, which should arrive mid March. So I can’t yet comment on their sound but after countless hours of research they appear to be the best Class D amps I could find under $5K.  

Happy listening.

I’ve only had them in my rig for a day, but I am very impressed. It blows the doors off my Willsenton R8. And I’m simply running balanced direct from my Pontus II. 
 

The bass is soooo much grippier and textured. I thought my soundstage was more or less limited by my Tecktons and my room boundaries. I was wrong. The AS’s fill the room with energy that gave me goose bumps and pushed to soundstage in every direction. I finally have speakers that disappear. I’ve been told they need 200hrs of break in. Vocals are gorgeous. I’m not missing tubes one bit. I feel like I’ve finally pierced above the clouds and my system is performing at a true “audiophile” level. 

I’m going to demo the Gold Note stack next weekend.
