I was already missed a lot because it is well known that the human ear is very tolerant of distortion at low frequencies. Hence, many specify the max power at 10% THD in class D amplifiers. The neophytes only look at the power data and strapole the entire band, without taking into account that at higher frequencies the maximum distortion must be 0.1% in SS and 1% in tube amps (from habit).
Thank you!
