Electronics do not have a break in period. You are only accommodating to the sound of your system.
This is also my thoughts.
For those that believe there is a break in period of electronics, please explain:
1. What is actually happening electronically that causes the equipment to sound better?
2. Why does the breakin process ALWAYS result in improved sound quality? Why is it not possible for whatever the breakin process is, to result in a less good (when compared to brand new) sounding piece of equipment at the end of its breakin process?
3. What prevents whatever the breakin process is, to stop when the equipment sounds better? Why doesn't it continue to breakin for its entire life and continue to improve?
