@ charles1dad,, I just got off the phone with the cable company, They said, High-fidelity cables are RCA only!, My main system only has XLR, and cast!, They said Rick will most likly develop XLR ends latter, that the ends is where most of his technlogy is at!, The cable company does not have the high-fidelity ultra cable yet, And to my astonishment, they said High-fidelity sounded very similar to Taralabs top cables!, when I told them that I had the Taralabs zero gold I/C, they said, none of the fidelity cables will beat the sound of the zero gold I/C, however, They did say that the ultra fidelity cable that is coming may be able to!, And of course, they said that it would all be system dependent!,, To tell you the truth, I am even more interested in High-fidelity cables now!,, all this is shocking news to me of how good these cables are after talking to the cable company!, Kudos to Rick!, Thankyou Charles1dad for your hospitality!,,, cheers!
