Best Digital RCA cable under $100 new or used?

Thanks for all your wonderful responses. I spent some time reading up on all the cables listed here. I boiled it down to two: the Auricle Audio Standard Digital and the Black Cat Veloce. I went ahead and ordered the Veloce. I would like to order the AA Standard Digital and have a proper duel but I see nowhere where AA has a return policy.

I haven't been through a lot of digital cables, but I have about 20 hours on a Black Cat Veloce, and I'm stunned. It's replacing an inexpensive Wireworld Chroma 5. If anyone ever again denies that a digital cable can make a difference, I will know now with 100% certainty that the person is WRONG. Of course, like everything else, a system has to have enough resolution to reveal the difference.

Veloce Black Cat is broken in. Wow! Very impressive. I am very satisfied. It brings out detail while allowing the tube amp to retain it's warmth. Running it with the very inexpensive Grant DAC9 (also used as a passive pre) and a Denon 2900 through Sound Dynamics 300TIs amplified by a Dynaco ST70. I feel guilty this is a second system...

Has anyone compared the Veloce with the Kimber DV60? I currently have the Kimber DV30 but I'm wondering if it's worth upgrading to either Veloce or the DV60. Many thanks

I second the DH Labs D-75 suggestion.
