Do speaker cables need a burn in period?

How do we define the flow of energy? Well energy
is the product of V*I (voltage * current). So you
see that current is only one variable. Votlage is
the other variable. Now if you say energy flows from
point A to point B then, the voltage at A is always
higher than B, no exception.

When the amp drives the speaker, since the energy flows
from the amp end to the speakers, the voltage at the amp
output is always higher than at the speakers inputs.
Therefore the electrons at the amp end of the cable always
subjected to a higher potential vs. at the speakers end
of the cable.

Diretinality is define as having a non-symmetric condition.
You have two variables here : current and voltage.
Current is symmetric but voltage is not symmetric.
Because of the non-symmetric nature of voltage, you have
directionality.

This is a fairly basic concept. It's first semester of
electrical engineering class. If you don't understand
that then you shouldn't let your incompetency waste other
people time. Nobody is going to bother collecting "data"
on something this basic. They probably got better things
to do.

Sorry, but energy is not equivalent to power. Nice try, though. Besides we already know that reversing the wire is what changes the sound.

I would agree with you.  Like I said, what I said is just theoretical.  Whether you can here the difference is well ... it depends on your system.

Yeah, it's semantic.  I probably should have used the word "power".
