RE: A Mercedes and a bus...

I understand the theory and agree with it as far as it goes.

Here's the problem: ALL musical signals contain some artifacts that are identical to common (to both leads) signals in some way-- at some time in the musical cascade (for want of a better term admittedly). Difference signals are not the ONLY components in music.

Push-pull operation applies CMR at certain points in the circuitry (it should-- the more the better-- for push-pull). So does balanced signal systems such as studio wiring, etc.

I'm not arguing that this doesn't occur. What I am saying is that S.E. amplifier operation and also S.E. signal wiring cannot reduce the Common Mode.

In MUSIC, that is an ADVANTAGE. In cleaning-up signal, it is a DISADVANTAGE.

No one is arguing how this works. We all agree here. What I am saying is that artifacts of real music have components that are identical with Common-Mode distortion.

The question before us is-- do we wish to reproduce that common-mode signal or do we want it to be attenuated?

Your answer will put you into one of two camps-- S.E. amps or push-pull. S.E. wiring or balanced?

I think that, in practical terms, all of us are using combinations of both.

The item here is that I understand what each is doing musically.
