I have recently tested the Kimber DV30 (your existing cable) in both stock RCA terminations, Pasternack 75 ohm RCA, and DH Labs RCA-750 termiantions. I have come to the conclusion that it's an okay cable, but really not that good. It does appear to have good resolution, but it comes across a little bright and messy and artifical. The poor man's Beldon 1694A from Blue Jean Cable still sounds better than the Kimber DV30.
A digitial cable can influence the sound of your system just as much as other things, such as interconnects, power cable, etc. Several of your possible choices are all silver or silver-plated items. The pure silver items can be very clean and clear, but they can also push too hard on the attack and resolution. It depends on how warm your system is and the type of sound you want. Another suggestion for more neutral digital cables are the Purist Audio Design.
