Power Cable Break In - Such a Change!

@mrskeptic This video explained it IMO. Jump to about 11 minutes in to speed it along. At about 24:30 minutes in, he explains break in.

What this video is suggesting to me is that cables are a terrible idea. Every time you move them at all you're degrading them in an audible way! What we need are cables that are built with the proper bend to fit between our components and then held in stiff harnesses to prevent them from being bent again. If we want to rearrange our components we're just going to have to buy new cables. Oh, but then there's the little flex cables that lead to the voice coil. They're being vibrated and flexed constantly. Those should be easily replaceable as they must be degrading at a rapid rate. How many hours are they good for? 

I don’t think about it too much. I do try to be gentle with cables because they certainly can suffer from wear and tear if they’re moved around a lot, mainly from the casing or insulator getting worn out. If a copper or silver strand is thin enough it can be flexed adequately to get it plugged in or unplugged without causing any significant crystal deformation. Enough cycles of flex below deformation can eventually lead to structural changes but you should be able to get millions, or maybe billions or even perhaps trillions of non deformation flexes out of a wire before it starts to degrade in a significant way. That’s why springs in scales can stay accurate for so long. For me, deformation that leads to obvious work hardening and embrittlement occurs with solid core wires, or multi strand when I’m working with bare wire ends and clamping them down into the amp or speaker.
