Best Digital RCA cable under $100 new or used?

I should add this is for a low cost second system between a Grant Dac9 and a Denon 2900. The budget is tight for this system. I am now using a Radio Shack one meter ($20) that sounds good at times but the music breaks up periodically and looses smoothness. I am betting it is jitter. So I want to move to a little better cable at a 1.5 meter length.

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.

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...
