@ozzy But if your system, and ears are not up to it, you might let this pass you by.
Exactly. Enjoy reading George’s history and mastery of cabling, and his associated explanations. For those who can’t hear a difference, buy cheap cables, save your $ and enjoy listening whatever you’ve got. Non-believers will likely never hear a difference, and whatever the case - only those who explore more will actually know and/or hear the difference. Some systems are not up to the task though...

With that, here’s what’s going on during cable break-in:
There are many factors that make cable break-in necessary and many reasons why the results vary. If you measure a new cable with a voltmeter you will see a standing voltage because good dielectrics make poor conductors. They hold a charge much like a rubbed cat’s fur on a dry day. It takes a while for this charge to equalize in the cable. Better cables often take longer to break-in. The best "air dielectric" techniques, such as PFA tube construction, have large non-conductive surfaces to hold charge, much like the cat on a dry day. ...
