QED Reference Audio 40 Signalkabel
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.
Like most interconnects here, the Reference Audio 40 is a silver-plated copper affair, arranged in a special complementary way – the two conductors have different diameters, and this is said to give an alternative path for high-frequency audio signals to avoid time smear. The foamed polyethylene dielectric is claimed to reduce the amount of signal lost to cable capacitance. QED’s Analoc plugs are fitted, said to be a low eddy current design with copper instead of brass used. They feature an outer locking cylinder that needs to be screwed forward before the plug’s ‘blades’ can be locked onto the RCA phono socket, then the locking cylinder needs to tightened backup for a (very) secure fit. The Signature Revelation speaker cable uses 10 silver-plated oxygen- free copper central conductors, which are claimed to provide very low resistance alongside high levels of detail. These cores are separately insulated and arranged around a hollow core of polyethylene; QED calls this its Aircore technology and it’s claimed to reduce inductance.
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.
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.
