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?

In all this bickering thread, has anyone actually burned in any cables lately? I’d love to see air as a dialectric get burned in. More popcorn please.
That’s why air is such a good dielectric, silly goose. It sounds good right out of the gate. Not everything takes the same period to burn in. Everyone knows that.
