Yes....but the problem is that most audiophiles talk
as if the signal goes along one of the speaker wires
then caomes back along the other. Phrases like "return
path" always appear.

But it simply doesn't work that way. The signal is AC,
so any talk of "directionality" is complete rubbish.
The current goes both ways along both wires.

 From what I can tell, most of them have no scientific
background whatsoever. Listen long enough and they all
eventually come out with something which shows this.

Power lines run at 15kV, that's a totally different
situation.

It's AC electricity...that means that electrons go
*both* ways along *both* of the wires. Anybody who
claims that "directional" cables make an audible
difference is as mistaken as somebody who claims
he can tell you what brand of hard disk you have
in your computer by listening to a .wav file played
from it.

What's needed is application of the scientific method.
Put the hard-disk guy in a room with five PCs and tell
him to name the brand of hard disk in each of them.

Put the speaker cable guys in a similar test.

Unfortunately it won't happen, or the test is always
badly designed so the listeners can talk their way out
of it when they fail - "It wasn't properly warmed up"
or something like that.

I've never seen what I would call a truly rigorous
test of these wild audiophile claims, and so long
as amplifier power cables need several months of
"break-in" then I expect that I never will.
