What is your favorite Class D amp?


Moving to a new home with a smaller dedicated listening room has caused me to rethink my entire system.  I have always been a fan of EL34 tube amps and presently have a Primaluna HP (4 tubes per channel), but the size and heat make this a bit more difficult in my new set up.  So I have been thinking about going with a smaller, less hot class D amp.  But being a tube guy, I have never seriously looked into or listen to these amps.

so what is your favorite class D amp?  New or used, in the 5k range, but could go up to 10k.  Preamp is a Conrad Johnson ET-7.  Speaker will be in the monitor/mini-monitor class (so I don’t need high power for a smallish room) but have not made my final decision on speakers as the amp/speaker synergy makes this kind of a joint decision.

I purposely asked for “favorite” to be a bit more open in your relies.

thanks, Bill

I also did not like the fact that my AS amplifiers had a mechanical transformer hum.

@peter_s This is the first I've ever heard of a mechanical noise issue with the class Ds! We'd have been happy to sort it out for you. 

Given that some integrated amps have entered the discussion, I am surprised no one has mentioned the Devialet Astra.

@atmasphere It was just a minor hum, but the intent was for a bedroom system, where absolute silence was desired.  I know you guys would have taken care of it!

@peter_s  Atmasphere GaN amps for a bedroom system?!?  Nice!  Makes me feel very poor. 🫩

The most advanced application of class D technology is provided by Mola Mola.  Owned by Hypex, Mola Mola's current stereo amp offering, known as the Perca, uses class D circuitry that is five generations beyond NCore (which they created).  This advanced circuitry is known as Trajectum.  Sonically it's an amazing amplifier regardless of what "class" of operation is employs.  In my experience it's an another level from other products utilizing class D.
