Paul Speltz' Anti-cables and Anti-ics are certainly worth considering. You're looking at $80 for the speaker cables, about $200 for 2 pair of ics that you need (less if you require RCA/single-ended terminations.
8 months ago, I purchased $260 worth of Anti-cables and Anti-ics from Paul Spelt and the performance far exceeded that of my $6500 (retail) worth of speaker cables and ics.
Some (including myself) consider the Anti-cables and Anti-ics an absolute best buy.
Note: I currently do not use the Anti-products as I am now using a more expensive cable which are simply the best I've heard to date. But the Speltz cablings are a close runner-up and I keep them for backup.
If you do a search on Agon for Anti-cables, Anti-ics, and/or Speltz, you will find that my opinion does not stand alone.
