Wayne, do you know of any proposals for alternative definition for measurment of Harmonic Distorsion? It is widely accepted that higher order harmonics are more offensive that lower harmonics and odd orders are more evil than even orders. I'm very surprised that tube-guys have not come up with their own weighted definition.I for one believe that measurement has value, but often time, we are not measuring the right things or not measuring them correctly.
