Copper: The second most conductive metal, and the most common choice for audio cables. Copper cables are perceived to have a more balanced, "warm" sound.
I’ve often wondered about this. I’ve got both silver and copper and have experienced a range with both. The thing I wonder is if copper is perceived to be more “balanced” because equipment may be more commonly voiced by designers using copper cables thus making silver sound bright by comparison. The flip side would be, if equipment was designed more with silver cables would copper then sound a little less balanced and a little overly warm or veiled? Probably a question for the ages, but as always system synergy and personal taste should be the final arbiter always regardless of metallurgy. But brass? Not when copper and even some silver cables can be had for (relatively) reasonable prices, which makes brass a non starter in my book.
