QED Signature Audio 40 Interconnect Cables - 1 Meter Pair - Closeout Sale

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 are the market leader but we’re certainly not complacent. Our design engineers constantly investigate new technologies and undertake scientific research to ensure we always offer our customers the very best products on the market. As far back as 1994 we conducted the most extensive ever scientific investigation into the effects of speaker cables on hi-fi system performance. The results were astonishing, and can be found on our website under the heading ‘The Genesis Report'. The report produced clear evidence that speaker cables do matter, and we continue to use this information today. We urge you to try QED cables for yourself. If you do you’ll discover the differences in sound quality that QED hi-fi cables can really make.

The groundbreaking Signature Audio 40 analog 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 maximize 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.

FEATURES AND BENEFITS

Complementary Conductor TechnologyTM

This innovation utilizes 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 copper

conductors 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.
