In my experience, the high frequencies took the longest to settle in during cable burn in and 100 hours is actually not a very long break in period. I have a Speltz Anticable from my tuner to my preamp and Jim Speltz recommends a break in time of 500 hours. I find this very funny since there is a 30 day return policy if not satisfied!! Anyway, based on your post, I think your setup will sound great when the Signal Cable is broken in completely. In my CD setup, I switched from Nordost SPM to a Cardas Golden Reference interconnect. I just felt that the SPM which is a silver cable was a bit strident at the top end. However, it was great when used between other components. Enjoy the transformation!!
