Do speaker cables need a burn in period?

blueranger,

"They settled down later."

Wouldn’t that mean that burn-in is not a permanent effect? Does the burn-in have to be repeated after, let’s say, a few weeks of vacation?

It would be exactly the opposite from...

"Have you heard the term electromigration? A current causes permanent changes in a wire"

Is there a third part that is missing between above two sentences?

This just in! Cardas explains cable break in.

"Cables, cats, pianos and rooms all need to relax in order to be at their best."

I knew my piano tuner has been robbing me. He is always tightening strings and telling me they got loose over time.

How on Earth do you relax a room?
