Hey Nego, you haven't been reading The Absolute Sound have you?
I've been around electronics long enough to hear break-in, and it usually is heard on mechanical equipment, ie, speakers or tube equipment, but never cables as they are, or should be a constant. I have tried many, many cables in my systems, and they are very revealing systems, and although I have heard many differences among different cables, I've never heard a cable to sound different over time. Many people here have tried that same experiment and have come up with the same results - cables don't break in. There is no evidence to support this either, other than what one person "thinks" he hears, which of course refers to faith. Cryogenically freezing cables, or microwaving cables, or lifting them up off the carpet, or arranging them in a North/South position carries no evidence of a change in signal - other than what one thinks he hears. Audio equipment performance is not, thankfully, based on faith but on scientific proof that measures a components performance. Anything that is not proven about a component, but instead is relayed as a belief, is nothing more than snake-oil. Unless a manufacture expresses that his cables sound better after being broken in over time and backs that statement up with scientific proof, I will not buy the cable, or the ocean front property in Arizona from him.
But then again, this is all just my opinion, and like assholes, we all have one.

If he hears a difference, who am I to tell him he does'nt. I like this hobby enough to try little experiments like these, which is what he is doing. He will learn, in time, what is real and what is illusion. :thmbsp:
