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!

Yeah, the designer couldn't have known how to make it sound as good as a snake oil salesman.
Thanks for the Love.....you and George must be buddies.....he he.

The fact is that everything makes a sonic difference and no one knows everything......so there are no perfect components. This is why all class A/B amps sound different from one another and same with class D. Every single thing you do makes the sound different. This means that many many people can improve on any one design. Not just snake
oilers...but even flat earthers.


Actually, I don't think much of him either.

Yes, everything makes a difference, the problem is not every difference is audible, nor will everyone perceive your "improvement" to be any sort of improvement at all. Tastes differ, so your operating thesis is flawed on two counts.

Have you any measured proof of actual performance improvements? No. You operate solely in the world of subjective suggestion. OOohhh! These new tar infused caps will take your amp to a whole new level! OOOh! And the sheep follow along.

You are like a parasite that lives off the hard work of others. You don't seem to offer any real products of your own, just mods to other people's work, with the marketing scam that your little tweaks will magically improve on all the heavy lifting done by the real engineers who designed the equipment. Every time some new amp or tech comes to market, there you are, pushing your latest oil on how to "improve" the product.

All you pedal is subjective bs, praying off the insecurity and obsessive, always in search of that magic mod to transform their equipment.

Sad.
Can't argue with a subjective opinion. It proves one thing only- you like it.

As for being an audio wizard and huge asset, you should save your praise for people like Bruno Putzkeys, who do more than wave their hands and ride on everyone else's coat tails.

The EVS 1200 is simply a stunningly great sounding amplifier. Stunning! Ric, you are an audio wizard and a huge asset to the DIY and audio community in general.  


Maybe on paper, George. However it's all about perception. It's all about how different people perceive sound differently. There is no universal best, regardless of schematic or
measurement.

Exactly!
Ric has taken the Ice boards and amp’s performance to the
next level.
Can you prove that objectively? No. It's your subjective opinion.

we get better sound
No, you get a different sound. Another subjective opinion parading as fact.

Sure people have been modding equipment forever, I never said there was anything wrong with modding. What I take issue with are these claims by these snake oil salesman that they have somehow "improved" the products they hack up. They haven't improved the performance, they have simply changed the sound. "Better sound", "performance up a level", these are all subjective and in the minds of the listener- not everyone who hears their changes would agree the sound is "better". Why is it some people prefer Purifi to tubes and others tubes to Purifi? Peoples subjective tastes differ.

that is what the new model is.....just a tweaked out older jobbie.

You really are clueless if you think all Bruno did with the Purifi design is "tweak" a few parts.




This gives noticeably better sound. No, it will not make it measure any different.

Trusting your ears is beneficial to getting great sound. Tru
Better for you maybe. Just more subjective bs. Like racing stripes on your car makes it go faster, lol. 

That’s your opinion vs technologies opinion.
The purest form of amplification if "done right" without any other flaws (except for heat) is Class-A, be it in opamps, tubes, or any solid state.

LOL, um, no, there is no "flawless" amplification class. Show me a class a amp that can match the purifi spec for spec, watt for watt.
I didn't say flawless


Really?
