cable break in

The speed of insulation polarization is comparable with speed of light so cable "breaks-in" as soon as you connect it to the signal.

Not a joke.
Read any introductory book on Electro-statics and there you'll find an answer.

cable manufacturers as well as dealers interested to pitch their product. thus to explain rediculousely high prices, sound becomes better after a few hundreds of hours of using just exactly what you need to psychologycally train yourself for that.

i may recommend non-introductory books as well but they require a prior basic knowlege to understand all differences between conductor, dielectric and semiconductor.

Folks the bottom line is (no brainer, realy) listening to cables is certainly different from listening to music. Another words is all that phenomena can only occur when you redirect your attention from tunes to wires.
