You'd enjoy thatinsider9 said:From my own acoustic measurements distinguishing an amp from THD figures is near impossible. And that includes valves, older and newer amps, budget and not. Speakers however contribute far more.
The point of % is also very valid as with volume as well as room interaction the percentage varies enormously. Noise floor also comes into play.
The beauty of measurements is that you do not predict or hypothesise. You do however need to be able to read them and understand what it is they describe.QuestForThe13thNote said:It’s all very theoretical and hypothetical and I don’t think you can predict things easily with too many variables, to the extent it’s not worth worrying about this stuff one way or tother in technical debate to the pursuit of good sq. Even if thd should or shouldn’t be a factor in an amp you make decisions on, you take the whole approach to looking at specs and most importantly listening. Things like price too.
im not sure I agree the point about harmonics being masked in the music. As anyway you listen and simply ask yourself does it sound better to me.
