Shadorne, you cheeky monkey, you.
Yes. I am being cynical again.....I know and accept that many will disagree but concerns about cable break in are,IMHO, bordering on paranoia...just play the music and enjoy it for goodness sake...
Frankly if a systems sound is making you so unhappy that you have to worry/fret about burn-in of cables then something is not right. A great system should make you ecstatic even with an unburned-in coat hanger for a speaker cable....
