Why do new cables needs to be "broken" ???


Could some one please explain me why do new cables needs to be run minimum 10 hours before the sound quality to stabilise ? What are the mechanical explanations ?
Thanks

First off let me say, I have no idea why cables need break-in nor I have I ever heard a satisfactory explanation for the phenomenon. Many here dismiss the phenomenon as non-existant because it can't be explained. There are many phenomenon whose existance is generally accepted without currently viable explanations. Really nothing new, happens all the time. Can't argue that a dose of skepticism isn't healthy. But to argue that cable break-in doesn't exist because its existance can't be scientifically proven goes against many audiophiles direct observations, including mine. Observation after all is the beginning of empiricism.
Quoting from the Stealth netsite:
"According to our point of view on the break-in process in cables, it mostly deals with the 'ground potential differences' in the componants used."
I quoted this because, perhaps the componants being connected are as important the connections in this process. I really don't know the reasons behind cable break-in and I don't think the cable manufacturers know either. What I do know is, depending on the cable, it can make a huge difference in the "sound" of a cable.
Break-in by & large is an urban legend, even for the golden earred in the boonies.
