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 did the tour with the Orchard Audio Starkrimson Stereo Ultra and had it in my system for about 9 days. It’s a fantastic amp — dynamic, great bass, good soundstage. It was better in many ways than my Belles Aria monoblocks but not enough to make me want to switch. I also spent a day listening to the Atmasphere Class D monoblocks. Also fantastic amps but felt that the Aria monoblocks were a little more dynamic and transparent. I feel like class A/B amps still have the edge but getting to be almost indistinguishable between the two.

Anyone also told they need a Variac for it to work?
 

@jcarcopo  I don’t quite understand your post.  What happened with your Ultra?  I used the Ultra for 2 weeks and had zero issues. I thought it was a great sounding amp.  It was not the dual mono version, though, but there are at least a couple of dual mono owners on another forum that are very happy with their amps.  Are you saying that you can’t just plug it into the wall and use it?  I’ve also exchanged a few emails with Leo and he was pretty responsive and helpful, so kind of surprised at your comments.
