IMHO most components don't break in. Your ears on the other hand do adjust to the new sound. Speakers possibly are the exception to this with mechanical parts moving air. Individual components in electronic audio gear have such tight tolerances they just don't change over short periods of time.
Interconnect Break In?
I'm wondering about break in on a new interconnect (RCA's). I'm using it from my CD player / Streamer to my preamp. If the CD player is on and streaming but the preamp is off, does the interconnect still break in?
If this has been answered and you can point me to that I'd appreciate it. I just didn't have any luck searching.
Thanks!
