RCA cables silver,gold or copper whats better?

your a better man then me charlie brown if you hear a difference. I would think in the long run there is less maintenance with gold. But copper has the advantage of no plating. Its up to your ears only.

My preference is silver plated copper (because that is what I currently am using). I will admit though the different manufacturers do not always have the same sound characteristics with a given type of wire. In other words I have heard both great and bad copper and silver but not really gold. To me personally gold is a little too warm sounding in cables for me. Maybe because I have a tube integrated.

Just my opinion

For me it seems to depend. I find silver to be more detailed and copper to have more body and bass. I mix and match per component.
