What are the best GaN Amplifiers available today?

Many believe you can hear things that you can measure, yet it is proven to be out of the ranges of human hearing.

like what you like, to hell with what others say. Like re soldering makes a difference. Only those that benefit monetarily act like they believe it makes a diff. 

Proposing a "tweak" is not the same as designing an amplifier..

For example i had a better experiment to propose about for sure what cannot be measured BUT could be heard :

Put a 250 gram of quartz on your amplifier...

Put a 250 gram of shungite on your amplifier...

Put the two together now...

You will hear a difference...

I fine tune my S. S. amplifier with these minerals tweaks... Really for the best...

But tweaking is not designing... No more than walking with better crutches are like installing an up to date prosthetic legs or growing a new one ..

And an improvement by design is always better than tweaking a design... So good the tweaks will be ... And they will if you know what you do with your ears...😊

But all of what we can learn from a component  and hearing if  we learn how to modify or tweaks it  are not all  measurable...If we tweak...

But if we design , all that we made MUST BE measurable, by defintion of a good design... And it is better if the designer as atamasphere know about harmonics for sure... And i will trust him precisely because of that...

And he knows that objectivist as subjectivist are deluded focussing on the gear but forgetting about psycho-acoustic basic ...

Just buy a certified good quality amp to start with and no need to take chances on tweaks.

You can also buy a cheaper amp and tweak it (void the warranty) and potentially have an amp that sounds a lot better. I have (or had) both great stock amps and tweaked amps. I listen to music a ton of hours each day on both types of amps.
