Gold plated
A reliable audio cable is by definition equipped with high quality connectors. This range of trustworthy connectors has a proven record of withstanding the harshest use that any rental or road application can throw at them.
The connectors that are fitted with gold plated contacts have the advantage of preventing oxidation and maintain performance after years of use. Another great property of gold is that it is an excellent electrical conductor. For comparison, if pure copper has a relative conductivity of 100 then gold is only 31% lower than copper, while nickel is 76% lower than copper.
These gold-plated connectors can be found in the pre-made cables of the Reference, Classic and Prime series.
