As I own a high end home theater system which has the expensive speakers, amplifiers and cables I always try to experiment to get the most out of the system. I was checking the performance of more expensive ICs than the RCA ICs. I use a beta tester from the person made cryo’ed RCA ICs. I found out that the performance was better for blue jeans cable. Please tell me are they any good but they sound good to me. Please help.
