Breaking in cables with FM static

I had not thought of that Bob, that would work just as well while maintaining peace and quite in the living space.

Why don't you just listen to some music, it will break in the cables and you get to LISTEN TO MUSIC, not static?

To clear a few things up, I am breaking in speaker cables, so the amp must be on. Two, I am not listening to the system 24/7, (I sleep at times); I have read that the white noise can speed the breakin process, so I thought I could do so at night. My concern is, can this constant white noise damage my speakers in any way? I have been running music from the tuner all night.

If volume is reasonable, ie not far above your normal music listening level, no damage will occur as the energy is spread evenly across the audio spectrum w/o transients. So yes, FM white noise is a very efficient way to break in all components downstream from your tuner, incl spkr cables and spkrs when you're away. To lessen the acoustic noise further without having to reduce the volume, wire one of the spkrs out of phase and place the spkrs facing each other: the radiated bass hiss will largely disappear.

The best cable "break-in" device is a cable cooker... There are several out there. Static is OK -- won't hurt the speakers or the amp unless the volume is too loud. I have also found the disks designed for system break-in / demagnetization to be more effective than FM static. My $.02
