Do speaker cables need a burn in period?


I have heard some say that speaker cables do need a 'burn in', and some say that its totally BS.
What say you?

Glubson, if my posts are not worth stalking me why stalkers thou me? Trying to be somebody, one supposes. My suggestion is a long cold shower. All the lonely stalkers, where do they all come from?

Is the hypothesis proposed that there is directionality inherent to wire, built into the physical structure and composition, even before it is ever connected to a voltage source, either DC or AC?

Or, is it that directionality becomes apparent only after connection to such voltage sources the hypothesis?

If the former, please explain what physical structures are fabricated into wire that determine directionality.

Otherwise, everyone here is simply full of it.
It's the latter.  It's only directional once you apply voltage and current.  

Now if you have a lot of time and you decide to swap ends on the cable every, say 5 minutes, while listening to music then it's no longer directional.
