Best Digital RCA cable under $100 new or used?

At $99, I found the Transparent Digital Link to be significantly better than other similarly priced RCA SP/DIFs I tried. It was smoother, more musical, less artificial sounding with more natural detail and bloom to the dynamics.

Apogee Wyde Eye. Canare connectors and true 75 Ohm cable. Found them to be very-very good. Could be bought from Sweetwater for below $100.

The Black Cat Veloce from The Cable Company is excellent and so is the Wireworld Starlight 6 and Morrow Audio DIG1. All three around $100 at the 1.5M lenght.

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.
