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!

I am saddened and bored by all these personal attack and confrontational posts. 

Things need to be kept honest here, if not this forum would have been overrun by fusers threads.
Instead of being shifted to the "Misc Audio" forum every-time one popped up here thank god by those that care and reporting them. (Should be call the BS forum)The admin here I don’t think are very technical, so they go with some of the tech heads here on these threads giving them info when reporting, but then there’s the sharks that pray on the gullible that say just enough to suck them in but not quite enough to get them deleted.(they are the used cars salesmen of audio)

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.
