I'm not sure an RCA version exists for the SP1000 cable. I did have an RCA version of the Monster Audiophile Cable Z200i which I was told by Monster was the same cable as the SP1000, just priced higher for us audiofools:O) The Z200i has been discontinued due to lack of sales and product confusion for Monster, even though it was their best sounding cable ever. So, that said, the RCA version of the SP1000 clone (Z200i) was very much in the same camp as far as performance. The XLR version has a slightly lower noise floor and more of a sense of ultimate power and slam, but almost identical otherwise.
