Many companies use dissimilar metals between the wire and connectors. We don't believe a silver connector belongs on a copper cable nor a copper connector on a silver cable. You will also find that all of our cables are equipped with a damping material within the connector eliminating resonance at the connector and RCA/XLR jacks they are connected to. This material also acts as an adhesive so please do not try to remove the connectors as damage will occur to the cable and will not be covered under warranty.
