QED Reference Audio 40 RCA Interconnects

Over 40 years of award winning expertise

All QED cables are designed using the top down principle. Reference Audio 40 represents the pinnacle of musical performance with only some minor concessions to economy when compared to our money no object Signature Audio 40 on which it is based. QED has won more What Hi-fi Awards than any other single brand and with the Reference cable range this heritage is delivered directly and without compromise. 

Complementary Conductor TechnologyTM

Unlike conventional analogue interconnects, Reference Audio 40 utilises two Silver Plated 99.999% Oxygen Free Copper 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. 

Analoc™ RCA locking plugs

The new QED AnalocTM plug uses a hollow oxygen free copper central pin to improve high frequency detail in the same way as our X-TubeTM speaker cables. To reduce swirling 'eddy currents' (that would otherwise oppose signal flow) a unique low mass plug design using two small, high purity copper ground leaves is used. Like putting wooden wheels on a Ferrari, conventional RCA phono plugs have the potential to undo all of the hard work carried out by our carefully designed cordage. With AnalocTM RCA plugs, the fidelity of the audio signal is maintained form start to finish.

Just listen

Our extensive listening tests comparing it against competitor products at much higher price points have astonished us! We urge you to compare it not only to your favourite cable but also alternative brands and models at any price!
