silver has about a 5% better conductivity than copper.. doubt it would be noticeable in many tests if at all.. I recently had some custom transformers built. I had asked for silver, which was quite a bit more expensive.. The designer/builder uses both copper and silver upon request. I was told that silver doesn’t sound any better and that I should stick to using copper. I was all ready to buy silver and pay the premium over cooper, but went with cooper after listening to the guy with 40+ years in designing and building transformers who could have easily taken my money and let me walk away paying almost twice the price…
