Do speaker cables need a burn in period?

So, many explain subjectively that they believe so.   Can anyone offer an explanation as to why this would make any difference?

i am trying to remain open-minded, but cannot see any explanation why this would make any difference.  

If if there is any difference, it seems to me adjusting to the character of the altered sound seems more likely.

again, I just want to hear one fact-based argument for “burning-in” speaker cables.

i see the reason for a car’s brakes - to heat treat the rotors evenly and burnish an set the pads, but I have never seen any explanation for speaker cables.

again, please  - someone - anyone - please provide some fact-based explanation as to why speaker cables may require breaking in.  I will keep an open mind, but I am unaware of why this would make any difference, or any factual attempt to measure such a difference.

Unless and until any plausible explanation is presented, I've got to call BS.  Please prove otherwise or at least suggest a theory?

I think it is more likely one perceives a difference rather than if one really exists with speaker cables.
