These effects are only applicable in cables that exceed one half
wavelength. The half wavelength of an electrical impulse oscillating
at 100K will be 3000 meters at most. If electrons in a wire travel at
1/10 of the speed of light in a vacuum then the half wavelength of a
20Khz tone will be 750 meters. It becomes pertinant at radio
frequences, where a 14 mhz signal is assumed to have a wavelength of
about 20 meters in air. A 14khz electromagnetic wave in air will have
a wavelenth a thousand times greater.

Sorry, I don't think your gonna have any 750 meter cables in your home
audio setup.


Nor is anyone else. The entire notion of wire affecting audio frequencies in
the lengths that people are apt to use is ridiculous.
