Power Cord Burn-In

Good, maybe we can use your expertise, once you give the idea of 'burning in' a chance.

I seriously doubt it.

It is true that 'quality' power cords cost more than Belden equivalents. Why they should sound 'better' is still a mystery. BUT, I know that Bob Crump, (my business partner in another company) INSISTS that his cords, both power and signal, MUST be broken in, to work at their best. He complains to me, all the time, that many people refuse to 'break in' his cables and this leads to rejection, or at least, disappointment. I have tried to understand this in physical terms, as I have a degree in physics as well. So far, I have only found 'interesting evidence' that points to a physical understanding.

Perhaps you can explain: "Faulted Defects Generated by the Movement of Boundaries in Electron Microscope Specimens" pp314-325 'ELECTRON MICROSCOPY OF INTERFACES IN METALS IN ALLOYS' CT Forwood, LM Clarebrough.
Essentially: "A striking property of high-angle grain boundaries in pure polycrystalline copper (99.999%Cu) is that they are mobile in thin-foil electron microscope specimens at room temperature and rotate during observation, preferentially at the surface intersections. ... The defects observed consist of different types of stacking fault bend, and in addition , small twinned grains sometimes form by boundary dissociation ... "
Various microphotographs are presented over a period of days, and the electron microscope was turned off between measurements.
Now, IF copper formations can actually move on their own, what would happen if an electric current was applied over the same time period?
Perhaps your model of electron flow shows what happens to these copper atoms and why they won't stay where they were first put.
