The groundbreaking Reference Audio 40 analogue audio interconnect celebrates QED’s 40 years at the forefront of British designed audio cables.
The Reference Audio 40 cable range is an entirely new design concept from QED labs. The cordage is designed primarily for low capacitance as this has been identified by QED as a significant factor which leads to a high fidelity experience, making for a tight sound and retaining the rhythm of the original piece. The Complementary Conductor Technology™ for high frequency detail and use of Analoc Technology™ to maximise signal integrity result in what maybe the most innovative interconnect ever made by QED.
Complementary Conductor Technology™
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.
ANALOC™ 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.
Foamed Polyethylene Dielectric
Foamed Polyethylene has a low dielectric constant and has been used to cut down on the amount of audio signal energy lost due to cable capacitance.
