Not bad, this is silver/copper alloy though. If it were down to that, I’d look into Mundorf Copper Angelique solid core, make an IC out of that.
Trial and error, I’ve found one needs to be careful with silver out there.. I bought some pure silver wire from a similar seller, similar dated website, and the sound was horrible. Turns out, he had some kind of jewelry friend, and made wire out of purified old silver jewelry - homemade style with chemicals, etc then pulled through to make wire. That was a $100 experiment down the tubes for me unfortunately. Xangsane product, I can say with a lot of experience doesn’t have that issue has carries exactly the silver sound one is after when looking at silver for IC.
