Cable run in burn in time

I'd tend to agree. As cable burn-in as about settling the dielectrics to their eventual extinction state (if you will), using an electronic device that may indeed damage them by overheating the active conductors is not a good idea. I'm fortunate that the dielectrics in my DIY PC Kits are simply Teflons, for which I successfully use a non-electrical burn-in processing. For fluorocarbons I had discovered back in the late 70s that the molding, tooling and extruding manufacturing process would result in a finished product state that still had mechanical stress potentials that would resolve ("cure") only over a VERY long period of time (months to at least one year). As the products manufactured were high-performance volumetric-measurement handtools (Pipetman, et al), it was mighty important to stabilize their structures before calibration so that they'd stay stable for their intended multi-year lives. My thinking is that since this same stabilization process (I'm calling it Enhanced Stabilization Technique for lack of a more inventive term) very measurably "settles" fluorocarbon products dimensionally, then there's quite apt to be an auditory correlate, since our ear-brains are far more sensitive than our labs' micrometers. So my take is that a "burn-in" process should get you where you're going eventually, and NOT provide an errant detour via an accidental over-processing, perhaps even ruining the performance of the product, as mentioned above. Users claim that my lowly $39 DIY PCs sound great right out of the box, and I suspect simply will change only VERY slightly with mechanical settling in over time...WITHOUT electro/mechanical machinatiing. Too bad this EST doesn't work on most cheaper dielectrics. Sigh....
