Default Audio Interconnect cable Performance - is Return Wire Diameter a Factor?

100% wrong. Any way you might choose to define "electricity", it under no circumstances
whatsoever moves much faster than the speed of light. Increase the voltage at one end
of the wire, "put more electricity in", if you will, and the effect of that cannot and will not
propogate along the conductor faster than and, indeed, as fast as the speed of light in
a vacuum. Indeed, it will travel significantly slower, for most conductor configurations,
on the orders of 30-60% slower.

Pop an electron into the system at one end, and that instant, one pops out at the other.


Nope, 100% wrong. It does not and CANNOT happen, in your words, "at that instant."

The water that one puts in a pipe is not the same water that comes out the other end
(unless the pipe was empty initially - not possible with electrons in a wire).


And continuing the analogy with water: stuffing water in one end of the pipe WILL NOT
result in water coming out the other end "at that instant", whether it is the same water
or not. It will take some time for the change in conditions to propagate down the pipe
before water starts coming out the other end.

With AC current,
it is entirely possible that no individual electron makes it down the entire length of the wire.


And, indeed, how would anyone possibly know if it is the same electron or not? And why
would anyone possibly care?
