Qed Audio 40

High-End Stereo kabel QED Signature Audio 40.

HI-FI CHOICE RECOMMENDED, MARCH 2014  

FEATURES AND BENEFITS

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 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.
