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 use Freya+ with Starkrimson monoblocks.

 

Whenever I use different tubes, it change tones.

I can make it sound fuller or sharper depending on vintage tubes.

Fortunately, I have more than 80 diffferent kinds of 6sn7 and variants.😀

I have had the Atma-Sphere Class D now for a couple of months and can't be happier. Sound stage is wide and sound is very real sounding to me, in my system. I liked the sound so much, I ended up upgrading a bit more of my system.

Now

PS Audio Power Plant 12 > Innuos Zen > Weiss DAC 502 > Atma-Sphere MP-3 > Atma-Sphere Class D > Rethm Saadhana

PC LessLoss 

IC XLR

Speaker Cable LessLoss with LessLoss firewall for loudspeakers

 

Happy Listening, all, on your own systems. I hope it brings you the same pleasure my system gives me.

I gave the PeachTree GAN400 a nice long trial run on my office Magnepan LRS+. I used a Holo Audio Serene preamp (amazing) and my trusty old Benchmark DAC3B.

The GAN400 drove the LRS+ very well. Almost as good as my CODA #16. However, the CODA #16 had much more engaging sound to it. If the GAN400 is 8.5/10 then the CODA was a 10/10. I used the CODA with a Benchmark LA4 preamp and DAC3B. However, those components were moved to my main rig so the GAN400 was purchased.

I put the Peachtree GAN1 (modded by EVS) back into the LRS+. It lacks a bit of power compared to the GAN400. I also need to move the volume dial on ROON higher than when using my preamps. However, it is a very engaging sound. Like the CODA #16 but with less deep power. This is tolerable with the LRS+ speakers and my small office.

The PeachTree GAN400 is being returned. It is good but the modded GAN1 is great, even if it could use a small boost in power for the LRS+. I got to figure out how to connect my KEF KC62 sub to the GAN1. It so much easier to hook up the sub when using a preamp like the LA4 or Serene.

Congrats OP on success with choosing an amp.

A whole thread on new class D amps and no love (nor mention) for the Nilai500?

Perhaps too inexpensive lol.

Im having success with a pair of these behind a Supratech preamp

I would love to hear more opinions about the Nilai500, I currently have DIY Ncore 400 monoblocks. Is it worth upgrading to the Nilai500? It supposed to be as good or even better than the Purifi amps. I am also considering the new Aavik amplifiers (I180/280/580) which are based on the Pascal modules.
