Do It Yourself (DIY) paradise for tube and SET project builders.

RE: What an astonishingly insightful (and iconoclastic) assessment of some formerly revered designs....

"Basically, push/pull is a processor in that it
possesses Common-Mode (any voltage that is common to
both sides of a differential circuit) Rejection,
called CMR by engineers."

No, push pull rejects any even ordered distortion created by the push pull (differential) circuit. It will not cancel any of the input signal.

"It is just common sense that this same circuitry
will also cancel-out any form of musical expression
that also occurs in the Common Mode."

There is no musical expression picked up by the microphone that occurs in the common mode.

The diaphragm outputs a single ended signal and it drives a single ended circuit that is coupled to the mic-pre through a output transformer who's secondary is connected through a balanced connection (that cannot cancel common mode signal because there is no such thing as common mode signal) to the input transformer of the mic-pre (that cannot cancel common mode signal because there is no such thing as common mode signal).

What a balanced connection does cancel is any noise picked up by the wire along the way, not the music signal or any part of the music signal.

Dennis, with every post you show more and more of your lack of understanding of how audio electronics work.
