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?

Yes, all cables require some 'break-in'.  Some needs more hours and some less. 
In my experience new cables sound worse at the beginning of their use, then settle down to their own sound.
Give them 300 hours of play, whatever you've got or going to get, and tell us what happened. The length of burn-in will vary, usually the better the cables the longer but not always.
