I also have a pair of 1 meter coincident ICs. I broke them in for more than 10 days straight paying from a CD Technics 110 disk changer as a source playing a variety of CDs. They sounded great out of the box but more mellow and defined after even 3 days breakin, and better as time went on. I've not tried any Wireworld cord, but respect the views of those who have. See Arthur Salvatore's site at http://www.high-endaudio.com/index_ac.html Good luck!
