Bob P. -- I ain't sayin' yes an' I ain't sayin' no neither.
What I'm saying is: I can't say for sure -- maybe it's all too subtle for my hearing (which ain't what it used to be!)
But, "break-in" changes with other devices in the audio chain (especially MC cartridges, tube gear, and certain kinds of speakers) are so obvious just from simple listening comparisons that it's easy to assume it must be true of cables and power cords too. And maybe they do change (doesn't everything?) The question is: are the changes significant enough to affect what you hear?
