Zd542. Regarding the break in of speakers. Seems to me that a speaker will break in better if music containing a wide variety of frequencies is used. Thus not all music is suited for breaking in a speaker properly.
I noted a dramatic difference in the quality of the sound when I eliminated the cheap IC's that came with my CD and replaced them with Golden Gate's by AQ. More neutral sounding the bass tightened up a bit. And then when I upgraded to the IC3 by Audio Art I noted an improvement in the sound stage and also more depth to the instruments.
I suppose if I had spent a grand or more on speakers I may not have needed to upgrade the IC's. But for the $100 I spent on the IC 3 pair and then $180 for the speakers (originally sold for nearly $500) I would have to say I have speakers that sound like they cost far more than I paid. :-)
