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?

Ok one more time. Explain to me when I accidentally cooked my ICs in my cable cookers speaker cable setting they sounded aweful. Lifeless, narrow soundstage and dull. They finally relaxed back (for a better term) out after a week. Hemigreg explain that?
now that this thread has been up well over a month, wondering if gawdbless is hearing any changes in his new/used cables...
I was also wondering should we look for gawdbless who is missing in action. He did it to us. Burned us all.
