QED Reference Audio 40

The revolutionary Reference Audio 40 analogue audio interconnect celebrates QED’s 40 years at the forefront of British designed audio cables

The 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. Add our Complementary Conductor TechnologyTM for high frequency detail and our Analoc TechnologyTM to maximise 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 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.

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.

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.
