Cabling is apparently my thing also - I have tried maybe 20+ pairs of speaker cables and almost as many IC's, all different price points. You know because you know Thiel, they have a very revealing, slightly lean, but extremely coherent sound. If mated right I have never heard a speaker with better timbre and tone to my ears. I do think lean is a slightly unfair description. They have such a clean midrange it can accentuated with cables or equipment with the same qualities. That IMO is why they can sound lean.
I am am currently using Kubala Sosna Fascination IC's (musical but clean), KS power cords which add clarity and no bloat, and Stereolab Diablo SC (small copper AWG, revealing yet musical - don't know how he achieved that, and very fast similar to Nordost. This is the best combo I have used. Although cables addicts like us can never say I am done haha...
