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!

Are there 50K amps? Only if you pay for it.. My ears couldn't hear the difference because their to darn greedy. Dog gone ears... Will not let my hands reach for anything over 10K, from my back pocket... Ears are to blame... Bad old ears.

One opinion, one man, the only one that counts MINE...

Every Class D I have heard is very good.  By that I mean near flawless. Not all created equal however.  Some might prefer  some tubes up front to embellish things a bit.

I have owned the AGD Audion amps for about a month now. They sound great i was a SET guy and the AGD's bring the best of SET and SS without the past flaws of class D.

AGD offers a trial period, i did this and had all intentions of sending them back but they surprised me at how good they were so i bought them and they continue to get better. Take the trial as i did and find for yourself it`s worth it.

To most Class-D's
Technics SE-R1 https://www.technics.com/us/products/r1/se-r1.html

Technics SU-R1000 (maybe) https://www.technics.com/us/products/reference-class/integrated-amplifier-su-r1000.html

But they probably still don’t quite reach the sound of the very best solid state high bias linear amps.

Cheers George

Underwood HiFi was launching a 200Wpc GAN amp for $3000 under the LSA brand that was supposed to bow around now so might be worth checking out.  Also, although I haven’t heard them from the few reviews I read the D-Sonic amps supposedly punch way above their price and offer a trial period.  Just a couple other potential options FWIW.  Let us know whatever you find, and best of luck.
