i am just skeptical -- as it isn't easy to isolate whether it is solely components or the mind or a combination of both that brings about such supposed audible change. i didn't even think about the wires, yet my experience with RCA listening demonstrates that different cables can sound different. though, as of yet i haven't experienced or even really attempted to hear if my cables change during the "burn-in" period. i can only say that most drivers, cartridges and a few digital sources have changed for the better, from minor to noticeable, during the break-in period.
