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 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.

I’ve never owned the Ncore 400’s but always wanted to try them. When I finally went to give them a try the Nilai500 had been released as their replacement.

This is the first time I’ve ever used class D for my stereo mains amplification.
I have Crowns for subwoofer duty, and I’ve tried using them for powering the left and right mains but they sounded just awful to me.

But not the Nilai. Very clean and powerful without the horrible edge (resulting in fatigue) that the Crowns presented.

The balanced line option (xlr) is also nice. Running fully balanced from start to finish is interesting… it really does seem to lower the noise floor in the room, being able to put your ear right up against 100db sensitivity horn loudspeakers and hear absolutely no hiss, hum or buzz of any kind is pretty remarkable in my opinion. I certainly could not do that with my unbalanced lines 

so far so good!

Good point about Nilai500. Would be great if someone heard them together with one of the GaN amps mentioned in this thread, especially those in the lower price bracket.
