Personally, I wouldn’t get hung up on Copper vs Silver windings
@lalitk @kennyc Totally agree - I became a SUT lover on "just" copper windings. In fact, tried the silver (Ag) version of Lundahl LL1931 (in a K&K box) versus the copper LL1931 in my VAC phono, and preferred copper (qualifying that a bit - the Lundahls aren’t my preference in general). Kevin Hayes of VAC has also told me he prefers the copper version, regardless of price. Not saying that can be extrapolated to other SUT makes - but copper ain’t bad! Sometimes I think that if copper cost over $1000 / oz, it would be the most desired audiophile wire metal BY FAR. We take for granted that it's so good, and affordable.
There is no substitute for trying things in your system and make an informed decision based on your own findings.
Also totally agree
