Ditto @jerrybj on the Black Cat Silverstar digital cable.
Not to muddy the waters, but I'm a fan of Duelund speaker cables and IC's. Pretty low cost and high value in my experience... and both the IC's and speaker cables can be had within your budget new or used. Parts Connexion carries them

If you can find them used, you can possibly avoid the 150-200 hour break in period for them to settle it. Often times posting a "wanted to buy" ad on Audiogon or Audiomart will generate some offers.
