Jean Hiraga modeling

Jean Hiraga idea :
"According to this view, an amplifier that produces dominant odd-order harmonics—behavior typical of push-pull designs—can never sound as natural as one in which both even and odd harmonics are present with progressively declining amplitudes."

Imbalance
Mind you that PP has even-order cancellation only in the ideal world. The imbalances in the PP pair, either random or intentional, will generate some even harmonics. I think Lynn Olson was using an intentional imbalance  in his Karm amp exactly for this purpose.

Credit Where Credit Is Due
Yes, all fine and good, but this notion was advanced by any number of people well before they heard it from Jean Hiraga (if they ever did).  And like "inaudible distortion", it turned out that there's more to it than "even order distortion".
