Stanhifi...do you listen to music or just measure it and talk about it! I've most likely owned more gear and cables then most. I have also talked to many learned audio guru's/owners of cable companies...most would not agree that over 2weeks of 24/7 break-in is beneficial. Most cable designs offer mostly inconsequential differences in the sonic presentation...not overall fundemental improvements. Everytime I have heard a properly setup system with MIT cables, the experience was nothing short of breathtaking.
