I ask because I've built myself an audio switcher that allows me to
remotely adjust the input impedance of my sound system amplifier from
my listening position. I find not only that each source device sounds
best working into a different input impedance, but that my preferred
input impedance for any particular source varies with the recorded
material being played through it.

What you are hearing is probably not related to the actual input impedance
issue. Electronics in general shouldn't care much about the load as long
as it's substantially higher than the output impedance. Dynamic mikes
are a very different thing; they are actual mechanical systems and the
impedance affects the mechanics.

You agree with what logic tells me.

The other problem with this is that you are probably changing level too,
and a tiny level change can mask all sorts of other things.

Possible, but making intentional tiny level changes doesn't get me
anywhere near the same result.
