Let's Give The Mod Another Chance to Ban Me!The simple truth is that resistance, inductance, and capacitance (R, L, and C) are the only cable parameters that affect performance in the range below radio frequencies.
In a published article even 11 of the audiophiles at Stereo Review were unable to tell the difference between expensive speaker cables and 16AWG lamp cord.
Surprised? Well you should not be.
As far as hearing, well the smallest step-change in amplitude that can be detected is about 0.3dB for a pure tone. In situations we are discussing (not in an audiologist's office) it is more realistic to say 0.5 to 1.0dB which is about a 10% change.
The smallest detectable change in frequency of a pure tone is about 0.2% in the band 500Hz-2kHz (in a booth at an audiologist's office) and this is the parameter for which the ear is most sensitive.
What's going on in these discussions of cable differences is circular reasoning (from Logics), that is the proposition to be proved (there is an actual difference among cables) is assumed at some point in the argument of which cable sounds better than another.
Let me quote a great science fiction, get that fiction, author Issac Asimov.
"Don't you believe in flying saucers, they ask me?
Don't you believe in telepathy? — in ancient astronauts? — in the Bermuda triangle? — in life after death?
No, I reply. No, no, no, no, and again no.
One person recently, goaded into desperation by the litany of unrelieved negation, burst out "Don't you believe in anything?"
"Yes", I said. "I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers.
I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be."
