Cable Break-in....again?

I recently purchased a used set of cables. According to the prior owner, the cables had been given roughly 120 hours of play time (the required break-in time according to the manufacturer). However, it seems that once I install the cables in my system, I can hear them break-in again, as if they were new.

Do you think that once a cable (either speaker or interconnect) has been disconnected for a period of time, they require another break-in period?
