I have a pair of 11 foot Kimber PBJ interconnects. They have locking RCA plugs...WBT knock offs. I constructed these from cable and plugs from Parts Connexion. I used them for a subwoofer that I no longer have. If you go to any retail site the 4m cables will be $243. I would like $190 shipped and I will eat PPal if needed. You could build 3-4 sets of shorter interconnects if you wanted to.
