Well in regard to break in , it has nothing to do with you remembering exactly what a component sounded like. It is actually more easy to hear what is happening. An example is that i just bought an Michi S5 power amp replacing my Accuphase E-470 , the thing is that for the first 20 hours it sounded really great , then came a period where it sounded almost like if you are getting a cold , after the 40 hours mark things turned better again , better bass , the whole picture was more precise.
At least that is my experience not only with this piece.
