Russ Hamm proved it in 1973 with his paper which

he knows it's true and will be until they change the laws of physics.

Hamm's paper was not peer-reviewed, and it was written so long ago
that it is irrelevant to modern amplifiers. The laws of physics have
not changed, but our ability to manufacture excellent SS devices
certainly has.

Worse still, Hamm considered only a very dated style of a.c. coupled common
emitter transistor amplifer without degeneration and the majority of his
conclusions were about its character when *overdriven * ! Simple. You avoid
'overdriving' !
