from pure science prospective "breaking in" cables is kinda nonsense....however as all kind of cables age micro cracks are developed in insulation and solder joints . making them worth over the years . cables will never be better over time. i wouldn’t worry about speaker wires ,besides banana or other type of connectors contacts or soldering there is nothing to worry about.
now about "break in" in electronics.electronic components age in time under heating and cooling conditions. resistors increase in value and capacitors decrease.it might be some changes in inductors . when scientific labs build very precise electronic meters they use aging process . they heat and cool components numerous times and then measure them for actual value.The value can change ...i would say under 5%. and then they build the device .So in our case of consumer electronics , components deviate 5-20% of stated value and the hole "enchilada" works just fine. there is no exact formula for "aging" electronic components .i would guesstimate "break in " period from 6 month to a year.would anybody hear the difference in sound? i doubt that very much ... will the system sounds better or worth ? it can go both ways...don’t forget that "break in" in speakers is more "dramatic" and happens only because of mechanical aspect. as semiconductors go, they work or they don’t.
My advice as a specialist in consumer electronics is .... do not use your system for the first 2 weeks in high volumes, so not to cause damage to speakers.... that's it..... enjoy !
