Output Z and speaker loading effects are a separate issue.

They are actually related.

A triode amp can easily have low output Z across the audio band, by use
of
NFB.

And we know that Jootikins preference as being discussed is for *zero*
NFB.

The hilarity is that the SET ( and indeed P-P ) output can only begin to
have
a *flat frequency response* and also lowish output Z by using serious NFB.

** The former is easy even with no loop feedback - fool.

go between them.

You're useless.

How do you think an active filter works ? Voodoo ?

I don't suppose a spice model would even convince you ?
