None of what you described has a real, audible effect on an audio signal. It would have one on signals of a much higher frequency, such is in the mhz or ghz, but audio is not transmitted at those frequencies.

Everything you said is completely bunk when it comes to what you can hear. The ONLY time cables matter is for speaker-wire, and it is very specifically gauging of the wire based on the length of the run and impedance of the transducers themselves. Choosing the wrong gauging can cause very measurable, detectable high-frequency roll-off.

Any other situation, there is 100% no difference whatsoever.
