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?

Clearly. Yet they sound great. Better than his previous cables which were directional 
Depends on what you mean by “directional.” All wire is directional.
yes, I should have been more clear.  I was told it didn't matter which end was attached to the amp and which to the speakers...that's as far as my technical expertise goes
A signal is a signal, right? Cable burn-in, seriously? I have been listening to hi-fi longer than a lot of you have been alive. I have never heard cables that sound better after burn-in and I don;t spend lots of money on speaker wire. If I have money to spend I spend it on something that will make a difference like upgrading components.
