Why do cables need break-in?


I just had the experience of having newly introduced speaker cables (AudioQuest AQ-8 bi-wire) break in. When I put them in a few days ago they sounded thin, bright and lacking in bass. Now, after 4 days and 40 - 50 hours, they sound far better: relatively neutral frequency spectrum with much more bass weight. I'm delighted, of course, but I'd like to know why this happens. Will I experience the same scenario when I change interconnects?

Sndsel, how about IQ testing and coaching of unintelligent electrons for the latest tweak? Might be some dough in it , if you market it right.
We might call it ACUE ...Assessment Center for Unintelligent Electrons.
Cheers!
Detlof, LOL! How about TRAINING thus challenged electrons to enhance their skills. Huge market: "Goodbuy expensive cabling, hello expensive (electrons) training!"

Sorry, Pendragn, I'm off subject.

Cheers!
