I have a wonderful cable that I putchased a while back that has been the single best addition to my system I have done in a while. I replaced 4 cables with these and I promise you they wont get disconnected again. The individual that engineered these prefers to stay anonymous for some reason. That was the only "downside" to buying. I have permission to release his contact info to only those who are really interested. It sounds kind of silly, but I am respectful of his wishes. I can say this much, the cables replaced approximately 6000 dollars worth of cables which included Nordost, Kimber and Virtual Dynamics. I sold those and made a profit when I subtracted the price of the new ones.
