Yeah I have read the same post here as well. But my in a few amps there seems to be a difference. I know I can definitely tell a difference between my Kenwood kac-1023 vs pretty much any other amp I have run including my old pg ms2.125 amps. Now between most class D amps, I agree 💯. But there is something to be said for a amp with a stout power supply. I guess I was too wordy but I was basically looking for what they felt was the best performing mono amp that didn't lose steam with extended low note passages.
