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!

Personal attack?  That was me being a lifestyle coach and suggesting you evaluate whether your energy is being well spent or not.

:-D

Hey George,

You've written like twenty thousand posts bashing Class D.

How many minds have you changed?

2?

Best,

Speaking of leaving your amps on or off:

From my own experience and several other A'goners, some Class D amps take a good 2 days of being on before they sound their best. If you listen to them in a store or turn them off while you are away keep this in mind. In my case I use IcePower 250 ASP amps which I know have this issue. You don't have to play music, just keep them on. 

Best,

I have not done a survey, but if you like laid back with plenty of bass, I can recommend ICEpower amps a great deal.
Kids !!

With amps that have automatic standby capabilities there is a combination of muting circuit AND de-energizing of the amplifier. First one, then the other. When the auto-on circuit senses a valid music signal it will reverse the process, energizing the amplifier first then disengaging the mute.

The auto-on sensing circuits draw power, but these are in the range of milliwatts.
Please @georgehifi , tell us all what an obnoxious poster looks like, cause most of audiogon has tried to explain that to you in detail and you’ve pretty much ignored them.
