Audiophile quality USB Cable.. does it exist?

FWIW, I asked this question about a year and a half ago, and at that time, no one thought it mattered or could recommend one. I went with one that had gold plated conductors (Belkin or Monster, not sure). I have occasionally used different USB cables without noticing any difference.

I looked at the Cardas and Kimber sites. I could not find a USB cable on either of them. Perhaps they have not updated their sites with them yet.
