It may sound odd but it surely was odd to me when I read comments about "break in" period for a CD player. I know i need to break in my new shoes so the leather softens and adjusts to my feet. So it happens with car engines where slight mechanical imperfections of the scale of pico meter are adjusted and it takes 2-3 months of running the engine at non very aggressive revs. When it comes to electronics that have no mechanical aspect in their performance, how do we do that break in. I read comments of some people talking about the first 300 hours. What is it that can make the sound come out better after that?
