Heres a little story;I lent an IC that had about a year in my system,to a non audiophile at work,this guy is a true music lover,anyway a week later he came over and said;"I cant believe it ,but im hearing details in music that ive not heard before,and it seems like i dont have to turn the volume up as much as i did before i put this IC in!He said he HADto get one of these ICs,so he ordered one,a few days after he got it he came over and said,"Geez,this cant be the same cable,it sounds terrible,im going to send it back,he must have changed the way he is making them ,it does not sound the same as the one you lent me,"Anyway i started to laugh,and explained that it will sound better soon and to leave it playing when he went to work,and sure enough ,a couple weeks later he was happy ,as the cable did sound as good as the cable that i lent him that was "broken in" go figure!
