WireWorld Uni-Term Silver Spade Speaker Cable Connectors (Set of 16)
Since silver is the most conductive metal, adding a layer of silver over copper can improve performance. The term ‘clad’ refers to an extremely thick layer of silver. The silver-clad cables have about three times as much silver as the related silver-plated model. Silver also makes the quietest and lowest loss connections, even when mated to terminals made of other metals. Silver conductors improve resolution, which can reveal colouration caused by design faults, but in the best designs, they simply reveal more music.OFC - Oxygen-Free Copper Conductor
