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 that 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 groundbreaking design.
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 has a low dielectric constant and has been used to cut down on the amount of audio signal energy lost due to cable capacitance.
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.
Silver Plated 99.999% Oxygen Free Copper (SPOFC) conductors with LDPE dielectric
Asymmetrical twisted pair geometry
OFC shield giving 100% electromagnetic screening
Zn/Mn ferrite Jacket
Gold plated QED 'Analoc™' RCA plus parallel Capacitance: 76 pF/m
Inductance: 0.37 μH/m
Loop resistance: 0.072 Ω/m
Dissipation Factor: 0.0059
QED Lifetime Guarantee
QED ‘Analoc™ RCA plug which features high purity copper signal and ground connections in an insulated low eddy current brass body. The hollow central pin eliminates skin effect in the signal connection and the locking barrel design clamps the dual tombstone ground connection firmly to the RCA sockets.
Complementary conductor geometry 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.
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 Anamate and Analoc RCA plugs, the fidelity of the audio signal is maintained form start to finish.
