Now to partly answer my own question, I came across
a great website that discusses the issues I'm pondering.
He titles the articles "Skin effect" but in fact spends very
little time on true skin effect.
http://www.st-andrews.ac.uk/~www_pa/...io/Analog.html
He does provide many graphs showing very clear effects
of different cable construction--all at about 100kHz, and
most less than 0.1dB-- but measurable and predictable,
nonetheless.

But NOT audible. This is the kind of "pathological" wacko
"pseudo-science" that people get hung up with when trying
to avoid the real world (for whatever reason?) The website
appears to do a good job of explaining the physics, but it
doesn't follow through with what effect (or not) you will
actually HEAR at audio frequencies.

That's Jim Lesurf's site. You'll find he's a regular poster in
uk.rec.audio, and he's by no means pathological. He would probably point
out that the information on the site is just that - information from
experimental observation. He deliberately does not draw conclusions
(probably, but I'm guessing, because he doesn't want to fan the flames).
He's a very good and thorough scientist, judging from his posts and his
books.

I believe he once designed amplifiers for Armstrong, and he's a very
knowledgeable chap. I think the website doesn't 'follow through' because
Jim simply didn't want it to.
