Best Digital Cable, Regardless of Price....

I've tried a few between my CEC TL-1X and Audio Logic 24MXL.
I'm currently using a Purist Audio Digital Link AES/EBU, which I'm very pleased with. I also have the Purist Digital Coaxial with RCA's, but the AES/EBU with XLR connectors does sound better.
I've heard a lot about, and would love to try, the Kharma Enigma -- new retail 1m $2750.

I would suggest trying your present cable with BNC terminations first. I'm not a big fan of RCA for digital. BNC and AES/EBU terminations are superior.

I haven't done much comparisons since I don't plan for my source setup to be long-term, but I have the Jena Labs Fugue digital cable and compared it to my PS Audio Xstream, which is regarded as a pretty sweet sounding cable. The Jena Labs digital cable beat it pretty handily. I was happy that I even heard the difference, and since I believe that Jena Labs cables can be a last stop in cables, I have not bothered trying anything else.

I believe a Dreamdancer digital cable can be made so that would probably be the ultimate for me.
