Keeping an IC broken-in…is this a good idea?

Hi Goners,  

To keep an extra unused interconnect cable broken-in, so that when needed it is at its best performance, my plan is to connect it to the TapeOut of the preamp and back to an unused Input on the same preamp.

Will this work?  Do you see any negative effects of doing this?   Could it affect the overall sound from the pre?

What do you folks think? Good idea or not.

Thanks.
