While I don't dispute the effect / necessity of break-in, a bad cable will sound bad no matter how much break-in you give. An new BWM won't drive like an Yugo during it's first 200-500 hours, just saying.
I may disagree if only a little. I once had a set of QED cables and initially they sound constricted as if the singers were out of breath, but after awhile it was nice and better.
