That’s actually a good comment, I made a very thorough research for the last minute, but only got to see the KEF reference with Cambridge Audio and Electrocompaniet electronics . From looking online I liked most what I read about Pass Labs A class amps - I liked the explanations and they measure pretty nice for non feedback amps. And I saw a used CH Precision, and well they’re gorgeous products . But I’m really not sure how all this really sounds different then good middle tier amps because I never did testing in real life
