Spelts interconnects silver ?

Yes, he does. I have a couple pairs of his 1.5m ICs. They are made with two lengths of a thinner gauge magnet wire, one for the center conductor of the RCA, and one for the outer housing of the RCA, which also acts to filter stray RF /EMI. He makes XLR ICs as well. BTW, these are not made from silver.

They are wonderful, G. Extremely good bang for the buck as well. They replaced three complete sets of ICs that I owned from 3 different mfgs, that retailed (per 1M pair) for $500, $900, and $1,300 respectively. If you like the Anti-cables, you will probably like the Anti-ICs. Are there better? Of course, but how much are you willing to spend to get that little extra?

Note: I do think the Anti-ICs are a little more system dependent than the Anti-Cables though, from listening to other systems with them. Both work very well in my system, though.

No silver on either that I'm aware of. Just solid copper magnet wire.
