Recall that there is no net flow of electons in an altenating current.
Here’s what I think is the fundamental reason why good power cables sound better than less expensive ones, or those with less sophisticated engineering.
Noise.
I think that better power cables have a higher degree of noise rejection from the line and, as a result, are not passing this on to the power transformer, power caps and beyond. That would translate into higher S/N, which the ear is quite sensitive to.
