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!

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.

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.
