I have Signal speaker cable and all three types of Signal PC's in my system. Very satisfied with this combination. On the I/C front, I have firsthand experience with all the brands mentioned in the original post ... and my opinion as to which is best can be summed up as "it depends". If you want the cleanest, purest sound (some may call it analytical), with the most detail ... then the Speltz Anti I/C's are the clear choice. IMO, they're great in the mids and highs, but not so strong on the low end. For the best in full bodied sound top to bottom, the AA IC-3's are the best ... with the Signal Cable Silver Resolution coming in very close behind. I think that may be due to the fact that - with the exception of Signal's Eichmann connectors - these I/C's have very similar geometry in the internal wiring ... silver plating over OF copper. To me they give a similar presentation ... smooth through entire range, with excellent details, midrange clarity, and tight authoritative bass. The AA IC-3's just do it a tiny bit better. That said, for my tastes and my system, if I could only have one I/C from among these choices I'd go with this order: 1)AA IC-3, 2)Signal SR, 3)Anti-IC's. At that same time, I could live with either one and not feel lacking or disappointed ... make sense?
FWIW ... between a multi-channel set-up, CDP, Pre, Tube buffer stage, and mains, there are quite a few I/C's at work. One not mentioned in the original thread is the LAT International IC-200. It retails for $279 for 1M pair. It is my personal favorite, and the I/C between CDP front L/R to Pre. I had an opportunity to A/B this against the AA IC-3, and it is the best of the bunch. Does everything the IC-3's do with just a bit more clarity and refinement.
