alphacore users break in question

They don't need break in because they are basically unshielded - AC will tell you that. I've had these very cables and what you describe is nothing like my experience. The zobel network will not change the sonics only keep your amp from oscillating. Sounds like a mismatch - maybe you need M3 or M1 can't remember for a higher amp wattage rating...but Steve is right 100 hours will be wasted if your waiting for burn in.

Well, that's a good question that may vary from system to system. When I used these cables with a Classe amp I noticed no difference in sound with the networks in or out, but when they were out the amp shutdown after a while of playing music.
