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.
