I see, your just regurgitating BS. All the usual: take real physical properties and stretch them till they show a difference though no one can hear a difference. Those articles talk about measurements but show none, why? Anything that one of the biggest snake oil salesmen, BS audio, is pushing can be ignored.
"In one tested cable, (the worst one we could fine, probably some wierd hifi cable) the speed of a 20,000 Hz signal is about 110-million m/sec. The speed of a 20 Hz signal is about 5-million m/sec," So the difference in arival time from 20hz, which is rare in music, (40hz would be better but then the difference is much smaller, the stretch part) to 20khz is about 1.5 usec. and probably 1/10 of that in the important 200hz to 8khz range. that 1.5usec is 1.5mm in travel distance for the worst possible case. Your driver mountings probably have lower tolerances.
"A cable is very reactive to voltage changes at low frequencies. This is because any capacitance absorbs low-frequency AC voltage changes, and starts to look like its carrying a DC signal." A capacitor is high impedance at low freqs. especially the tiny amount in a cable. So how does it "absorb" anything at low freqs.?
The BS continues with impedance matching and skin depth. all of which has been measured and debunked.
