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?

I have always run my speaker wires on a slight downhill grade from the amp to the speaker.  You will hear the difference right away.
It's really surprising that the various makes of cable elevators don't come in graduated heights so that one can achieve that downhill effect more easily.
The question to ask (from my college Psychology 101) is can you step into the same river twice?

In the same vein, can you listen to music on the same cable twice?
