Do cables need to be re-broken in?


Say you don’t use them for a while. Is there a time needed for them to be broken in again?

People with lousy (nonexistent) listening skills love to crack jokes. The differences some of these things make are beyond easy to hear. One time I came home to a new IC and with little time between shifts raced to hook it up right out of the box. It was a used cable, should have been broken in, sounded absolutely horrible. Not imperfect, not disappointing, not bad. Horrible. Awful. Bad enough I lost sleep that night wondering what might have gone wrong. 

The next day at work it dawned on me, I didn't recall checking direction. That night first thing sure enough it was backwards. Switched around and warmed up it still needed a few hours to settle in but now it sounded really good.

These things do happen. They do make a difference. Just not a difference everyone is able to hear. That much at least is clear.
Bob Crump of TG Audio broke in all cables and power cords for 30 days on M.O.B.I.E. prior to shipping. The presumption is that cables or power cords NEVER break in 100% just playing music through them, not even in ten years. Maybe not even 80%.  Please, no angry PMs.
I know my house wiring hasn't broken in it takes 10 seconds to long to cook my oatmeal.
