Whew, what a lot of work! Thanks for your contribution!

Perhaps you could answer a question for me. There's something that I don't understand about the graphs of Harmonic Distortion % by Component. How is it possible that, in I think all the tests I've read so far, the second (and sometimes other) harmonic % curve is higher than the THD % curve for the same drive level, even accounting for frequency response and power compression? In some cases, the H2 or H3 measured distortion seems much higher than THD. What is the relation between the Harmonic Distortion % by Component graph and the THD graph exactly?

Thanks in advance for the explanation!

Maybe it's due to the weighting?

Thanks for the reply. I see there's more discussion of this on another forum, so I'll follow the thread there.
