I looked at it in the lab w/ a signal analyzer in years gone by when a

Laughable folly to any acoustic engineer.

It is fruitless, if not impossible, to compare the non-linear,
physiological properties of human hearing to a instrument signal
analyzer ... period, zero, zip, nada ... any comparison simply does not
_scientifically_ equate.

You can't (and no
one else can) hear what isn't there

Wanna bet?

A very common (due to psychoacoustic properties of the human ear)
phenomenon in the studio is a "ghost sound" on a recording; a sound not
actually physically recorded, but heard very clearly when two or more
tracks are combined to excite partials and overtones ...

.... IOW, you are indeed "hearing what isn't there".

Last, first...

But then it is there, but it's generated past the wire in the air and
that can, indeed, be measured.

For the point of what matters regarding the wiring, it _is_ exactly
equatable. *If, given the same inputs, there is no attenuation or
amplification or distortion in the wire that is discernible, then the
output will be indiscernible audibly if that input is converted to sound
by the same speaker.

Whatever is generated owing to distortion, harmonics, etc., etc., in the
speaker and the environment is there, certainly, but it had nothing to
do w/ the two wires over which the output of the amplifier was
transmitted to the speaker.

People here have yet to touch on how the complex impedance of a cross-
over network presents itself to an amplifier and how it affects its
linearity. Speaker wire, when conductors are close together can create
an inductive load (however small) which will affect that complex
impedance which can create a load difference between two types of
wires. A proper spectrum analyzer, one that can show a waterfall of
complex impedance, will not necessarily show an amplitude linearity
problem, but phase can be out of step over the spectrum. Speaker wires
can create different loads to an amplifier, which WILL make them sound
different.

always somebody stirring up the pot...
