My goal is to inform people so they can improve their stereo or their lives....that is what I do. The mods I suggested are completely universal. If you did this to a $400 Topping or a $120,000 Gryphon amp the results would be the same....except you would hear more difference with the more transparent piece of gear.
OK, quick logic check here; If "everything has a sound" (nonsense IMO, but...) then the "mods" you suggest will *alter* (key word here, not Improve) the sound of any of these amps. Again, doubtful IMO, but let's say you're correct. I know nothing about Atma-Sphere or his products, but from reading what he's written here, he clearly designs his amplifiers to *sound* right/good/pick an adjective to him, and hopefully, by extension to his customers. Nelson Pass is famous for designing amps with specific, and different, sound characteristics, i.e. not "flat" or "straight wire with gain". Again, he designs his amplifiers to *sound* as he intends them to, as does Atma-Sphere. So your "mods", to the extent they make any difference, only improve the sound *relative to your opinion* - nothing remotely universal about it - because every mod you do moves the sound away from the intent of the designer. You are setting yourself up as the universal arbiter of differences in *preference*, while also impugning the competence of every product designer out there. Good luck getting anyone to buy into that.
And for anyone dropping $120K on an amplifier that they don't think sounds right, or has a sonic signature that needs "fixed", well, I'd say meds are more in order than tweaks.
