Very happy with Speltz Anti-Cable IC's between my preamp and Sony SCD-1, and Anti-Cable speaker cables between my amps and De Capos (spades on amp end, bare wire into the bottom pair of binding posts). I also made a two pairs of jumpers from some spare Anti-Cable I wasn't using. (BTW, my amps are Quicksilver Mini Mites, preamp is a Quicksilver Linestage.)
FWIW, the Speltz stuff replaced Kimber SilverStreak ICs and homebrew Home Depot extension cord speaker wire. I'm still using Quicksilver's own silver ICs between amps and preamp, but I am considering trying another pair of Anti-Cables there just for fun. Certainly can't beat the price.
