New in factory box Qed Signature audio 40 Analogue Interconnects in optional length 2RCA-2RCA L/R-Channel (Stereo pair)
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.
Complementary Conductor TechnologyTM
All-new Analoc2™ connector design
The Analoc2™ design still features low bulk, high purity copper connectors alongside low mass metal barrels, but now cleverly substitutes high rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the detrimental effects of eddy currents. Although already smaller than in traditional bulk brass plugs, these unfavourable currents were still able to circulate weakly in the isolated metal body of the previous plug design. Now with the new material in place, these remnant resonant distortions are completely prevented from adversely affecting the information contained in the audio signal as it travels through the new plug.
To complete the RCA plug’s Analoc2™ upgrade and to help combat the skin effect, the hollow, rhodium-plated, high-purity copper signal-pins are retained, while the effectiveness of the slip ring which locks in place the similarly plated, pure copper ground-terminal as the barrels are tightened, has also been improved.
QED Analoc2™ RCA plugs feature high-purity copper signal and ground connections supported by a new non-conductive low eddy
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
