If you are writing about cables, just moving the cables around, bending them, unbending them.. messes up the 'break-in'. Ditto after a cable is cryo'ed. The more you bend/twist it, the the more "un-cryo'ed" it's going to be.
And has anyone had experience with a cryo'ed cable, that was so rebent, retwisted and replaced after the cryo, it totally lost all the benefits of the cryo?
Ditto single crystal copper cables, the more they get bent, twisted, replaced and recoiled again.. the more broken up the crystaline structure will be. (One reason to be careful about used cables of this type!)
