Silver will give you abit more air and detail but more neutral
people forget the connectors ,rhodium is abit more neutral then gold plating
silver also I prefer gold over copper,
many company use cheap gold over brass , most IEC ,and connectors on equipment ,even. Most cheaper speakers use gold over brass connectors
i replaced everything in my audio system that was not name brand copper
iuse only WBT, and Furutech IEC , connectors and connectors for power cords,
speakers WBT ,and all XLR,rca WBT. The system sounds at least 10% better just by upgrading all the connectors . Wireworld Eclipse use Silver over High purity Copper ,which is very respectable and 6-9s pureCopper ,great quality and value.
