For ICs, I just got a pair of the Mac (Myaudiocables) Palladium and its by far the best IC I've heard. Beat my APL Silvers and Luminous Audio Sychestra Reference, which I happen to think are good cables. I use all tube equipment, by the way. Speaker cables I recommend Luminous Audio Synchestra Signatures. They are the best I've had so far and not too unreasonably priced. Beat the Cardas Cross I had before that. Just my experience in my system, room, tastes, etc.
