FWD: re: Cables have direction/direction
andy, it's true that the voltage swing isn't instantanious, but it does
alternate between pushing electrons and pulling them. assuming it happens
at the speed of light, and we are not talking about running a guitar cable
to mars, the flow of electrons does indeed go both ways...it is
alternating directions, but is directional at any single point in time.
"sound" is transmited in both directions (pulling and pushing), and they
are roughly equal amplitudes.
the way you put it, yes, the electrons do move from one end of the cable
to the other, but they always move back the other direction as well.
i think hans has the right idea...the only directional issue with regards
to audio cables is how it's grounded. this might have an effect, if so,
the better your grounding to begin with, the less importance the direction
of the cable would make..and only if the shield is grounded at only one
