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.
