Basically, NO DIFFERENCE.
Others who claim otherwise need to see audiologists as usual is the case in this forum.
If that’s been your personal listening experience, then so be it. It’s quite a contrast from mine. Very easily heard and distinct differences in my audio system. People will have different outcomes. I don’t disregard yours and you shouldn’t disregard mine. Quality silver cables are unquestionably a sonic benefit in my system.
