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 TechnologyTM for high frequency detail and our Analoc TechnologyTM 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 ground breaking design.

Complementary Conductor TechnologyTM

This innovation 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

This material with its low dielectric constant has been used to cut down on the amount of audio signal energy lost due to cable capacitance.

Cryogenic treatment

It is understood that cryogenic treatment results in the elimination of dislocations and fractures in the material’s micro-structure. Trumpets and other brass instruments have been found to produce a better tone after Deep Cryogenic Treatment (below -190 °C, -310 °F) and it also extends their working life. Our extensive listening tests have shown that the cryogenically treated cable is preferred over the same cable without the treatment.

ANALOCTM Locking RCA Plugs

The new QED Analoc™ plug is a low eddy current design featuring small high purity copperconductors in place of the usual large volume brass body found in ordinary high quality plugs. This cuts down or eliminates the tendency for the changing magnetic field in the conductor to induce eddy currents which can affect the micro timing of the audio signal. Rhodium plating has the advantage for use as a plating material due to its superior hardness.

QED CABLES

Founded by Bob Abraham and Ian Vine in 1973; QED has, over the past 40 years, acquired unparalleled knowledge and experience of hi-fi and home cinema cables and connectivity.

We can also legitimately claim that, during this period, we have changed people’s perspectives about hi-fi cables. Consumers no longer believe that ‘bell wire will do’ or that ‘any old cable will be fine’. This understanding that cable quality is important and makes a real difference to your enjoyment began with the launch of the QED 79 strand speaker cable in 1978. QED’s reputation for both innovation and technical excellence is known throughout the world. The latest computer aided design techniques allow our research and development team to keep pace with technological advances and deliver products that achieve the highest levels of performance and reliability. This is why QED speaker cables and interconnects are recommended by so many of the world’s leading manufacturers of hi-fi and home theatre equipment, and also why so many of our products have won prestigious awards. For your convenience, and to better understand the different cable products we offer, we have divided them into four separate ranges: Profile, Performance, Reference and Supremus.
