Well, I received the Fusions on Fri., I put about 11 hrs. on them so far. These are the first cables I’ve tried, that went thru many changes in sound in my system. Zavfino’s website states; their fabrication prosses, equals 30 to 40 hours of break in time. So that gives me 40/50 hrs. on mine. I’m hoping that they will settle in around 20 hrs. of me spinning vinyl. So far I’m I’m impressed after the 9 hr. mark, I could only imagine the sound when they're fully broken in! TBC
