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?

If a dealer had demonstrated or/and sold a cable, for some US $3,000.- plus, and unfortunately it is not delivering the promised superiority: What could that dealer or sales person say?
"It will open up and sound better after a burn in".
Only three posts in and you are way too clear-sighted and logical. Stick around, things become murkier over time.Β
