I agree with Elizabeth. Hand tightened to snug is just right. Never use pliers,etc. to tork it on. You can even over-tighten it with your hands and it can be a nightmare getting them off. I had some AZ interconnects that I over-tightened one time and you don't even want to know the damage I did to the connectors just to get them off. I believe the procedure is, clockwise to loosen, counter-clockwise to tighten. Remember, snug is enough. Enjoy your new cables.
RCA interconnects
So, I just received PS Audio Transcendent interconnects. Problem is, I cannot get them to mate with my equipment! Short of destroying the equipment or one's hands, how do you soften these suckers up so they will mate? Is there some trick anyone has discovered that will soften the clamping power? What is the trick?
