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?

I prefer cables isolated from floor on maple blocks/sticks, like Pro Gold on connectors,  never tried cryo.  always followed manufacturer on direction, current cables non-directional according to designer...
Your cable guy must not have gotten the memo. Also, nothing wrong with maple blocks but I don’t think they are doing much vibration wise since the maple blocks provide a clear path for vibration. 
Clearly. Yet they sound great. Better than his previous cables which were directional
