GaN amps: Peachtree or LSA Voyager?

@atmasphere 

I see and understand your point. As a designer/manufacturer you have to be involved with measurement. And the quality of your work speaks for itself.

Tweak1's point is also a good one. As a consumer with little to no background in electronics, most of the displayed specs for any piece of gear are simply beyond my understanding. Yes, I could undertake to educate myself, but I simply have no interest in that aspect of it. So while it might put me at a disadvantage in purchasing new gear, I gather whatever info I can from various sources (I'm the OP) but ultimately it is my ears/perception of the piece in my system that will decide if it stays. 

Rick can speak for himself, but I suspect he falls somewhere in the middle. I doubt very much if he has access to the kind of testing equipment you use.

My audio experience is quiet extensive, going back some 30 years before I was a partner in Audio Tweakers in the early 2000s.
 

If you understood why your subjective opinions and experiences mean nothing to anyone outside of yourself perhaps you wouldn't post this logical fallacy called an appeal to authority, in this case your own.

Read carefully what @atmasphere has written.

Sure, you can trust your own ears, and ignore the measurements and science, that's fine for you. The problem is there is no reason for me nor anyone else to trust your ears.

Like it or not, an amplifier is defined asa device that increases the amplitude of a signal as high in fidelity as possible. We can use science to evaluate its performance as an amplifier. Some people want a wire with gain. Others prefer sweet distortion. To each his own. When an amplifier fails in a gross way to achieve it's design objective due to variable frequency response with load, it's not a good amplifier. It may make you happy, but it's not a good amplifier by definition.

As to the tweaks that can't be measured or substantiated in any scientific or objective way, they are fraud, pure and simple. If you and others want to shell out money and support the charlatans who are all too happy to take your money, please feel free to continue to prove PT Barnum correct, as so many others have.

you should read the crap you wrote in your own response as well as Ralph's

but I know you won't figure it out, so no further response from me

When you have no logical argument to make and can’t support your position with facts or reason, the best thing to do is to just shut up and go away. At least you understand that.

I am a scientist, a bit too far from audio engineering though. I have no time and also no desire to get deep enough into audio engineering science.  Nevertheless, this is a challenging field for me, because of my passion to music. Regardless of all the speculations and above debates, not being able to verify the arguments of each of you, my intuition inclines me towards @kuribo and ​​​​@atmasphere judgment. In fact, my current homework is to clarify for myself, which class D amp would be a best choice for me, or if it rather would be better to wait for a while until some clarity will come. I already tried a number class D amps helped me to learne something, and would like to find even better paths towards the same direction.
