It has been my experience that the components will change to a warmer sound after an hour or so of listening, not the cables, but I can't say with certainty that the cables don't warm up and change also.
I leave my system powered on so I get the best performance as soon as I start to listen. However, I am not using a Krell which I would not leave on when not in use.
Good Luck.
