Class D amps that are superior to all or most?


Recently, I have heard about some Class D amps that may be close to the best there is regardless of class. Certainly, this technology has been in development for decades. The main issue has always been the switching power supply. In this regard, I have taken notice of AGD. They have created a whole new power supply that “switches” at a frequency 100 times the normal silicon based MOSFET. The designer uses a gallium nitride based PS. Interesting, it is enclosed in the KT88 glass envelope that sits on top of his amps. I am aware of two more pricey amps that seem to be also at the top- the Solution and the Merrill. There must be others that compete for the title. After my thread, “Is there a SS amp that can satisfy a SET guy?”, I am still on the quest.
Don’t want to spend $50K!

Worse.

With a UCS, at least you got a car, condition somewhat indeterminate.

Some here are peddling pure ephemera.
Just your opinion. The fact is that most people are "fusers" or "tweakers" or whatever you call it. Even those who do not believe in fuses....do other tweaky things you would not approve of. It’s funny that you say we would be overrun by fuser (tweaks) threads........this is truly an admission to the fact that the non tweakers are a minority trying to stop people from enjoying themselves.

The ones that hate fuses and tweaks are a very small minority. But some of these people are adamant about stopping most peoples wishes. They (you, for instance) post every time someone mentions tweaking. There are lots of manufacturers who do super tweaking.....lots of them. This is a fact, and you know it.

The "honest" truth is......you like to argue and be right and put people down. This is your main reason for being here. This is why you have all those put down captions. We can all see through your game.....and I am surprised the mods have not stopped your constant put downs.

Tweakers and non tweakers can live together and do not need to confront one another. If you do not like what someone has to say about tweaking...then move on. Stop being so confrontational. You think you are doing the world a favor? If you really want to help people.....become a better, more loving human being. Let the tweakers have their dance.....and you can have your dance.....while we all smile.



Just your opinion.

NO!!!!

Like I said.
Hey all I asked was give us something, anything at all, to back this statement up of yours below, that’s all, nothing more nothing less.

You can see the insides of the Voyager on Underwood’s site. You will want it modified. Lots to do there.

How georgie jumped from what constitutes muting to fusers is beyond human ken. No logic. No reason. Just name calling for the sake of it.

And to top it all off, his appeals to a phantom mod system that watches and waits to what he reports back to them is the stuff of fantasy or a very poor attempt to scare people off of enjoying themselves and relating their experiences. 

All the best,

In response to OP’s question, a number of people here have pointed to GaN technology and specifically the AGD Audion mono blocks. I have these amps now for a few weeks and second the positive sentiment.
My signal chain is Roon (on MacBook Pro) via WiFi (Linksys Mesh) to OPPO 205 to (XLR analog) DSPeaker X4 to AGD Audion to Viking Acoustics Berlin MkII. X4 crosses to 15” sealed Rythmik sub below 50Hz.

The amps sound wonderful. Endless detail, texture, spatial detail even at very low volume. No listening fatigue. Relative to my (obviously limited, but meaningful over the years) experience, these amps are a discrete innovation worth listening to.
