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.

Won't an oscillating amp affect sonics?

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.

I just wanted to give an update. After 100 hrs I am pleasantly surprised to say the MI2 cables are sounding very good. They still are not quite there but I am confident they will continue to break in and get better. I guess it all boils down to system synergy and room acoustics since I am having very different results from all who were kind enough to respond. In my system in my room the improvement has been monumental after 100 hrs. Like going from zip cord to high end cable. That drastic.

Sorry, I just realized I used the dreaded "S" word in my last post.
