QED SIGNATURE Audio 40

The groundbreaking Signature Audio 40 analogue audio interconnect celebrates QED's 40 years at the forefront of British designed audio cables

Signature Audio 40 is an entirely new design concept from QED laboratories. The cordage is designed primarily for low capacitance as this has been identified by QED as a significant factor leading to a high-fidelity experience and makes for a tight sound retaining the rhythm of the original piece. Add our Complementary Conductor Technology™ for high frequency detail and our Analoc2™ technology to maximise signal integrity and the result is what we feel to be the most innovative interconnect ever made by QED. Please see our 'cables matter' section below for more in-depth information on this groundbreaking design.

  • EFlex Cordage
  • Low loss dielectric air gap
  • 3.5 mm Jack
  • Complementary Conductor Technology
  • Analoc2™ Technology
Analoc2™ Technology

QED Analoc2™ RCA plugs feature high-purity copper signal and ground connections supported by a new non-conductive low eddy current body. The hollow central pin eliminates the skin effect at high frequencies and the revised locking barrel design clamps the dual blade ground connection firmly to the RCA sockets for improved noise rejection. The all new Analoc2™ design cleverly substitutes high rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the distorting effects of eddy currents, which are always present in ordinary plugs where bulk brass is used instead

Complementary Conductor Technology

Complementary conductor geometry 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.

  • Teflon dielectric reduces audio signal energy loss
  • Deep cryogenic treatment improves signal fidelity
  • Analoc2TM using thermoplastic material minimises resonant distortion in the plug
  • Complementary conductor technology provides an alternative signal path for high frequency information
