The QED Signature Audio 40 not only celebrates forty years of innovation by the UK’s best cable manufacturers but it’s designed with the very best hi-fi equipment in mind. Lavishly indulgent materials are used here; pure silver-plated OFC conductors, Teflon™ dielectrics, Rhodium-plated RCA plugs. If money isn’t really an obstacle and you simply desire the best then Signature Audio 40 is a cable that will deliver pure satisfaction.

The innovative Complimentary Conductor Technology™ utilises two conductors of different diameters to carry the same audio signal. This has the effect of providing an alternative path for high frequency audio components which might otherwise become time smeared in a single audio pathway. The dielectric is made from Foamed Polyethylene has been used to cut down on the amount of audio signal energy lost due to cable capacitance.

The QED Signature Audio 40 RCA plugs feature an Analoc™ locking plug design, a low eddy current which swaps the usual large volume brass body for small high purity copper conductors. Each plug is Rhodium-plated with this expensive material’s hardness offering both maximum durability and a sublime connection between plug and socket.
