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 their Complementary Conductor Technology™ for high frequency detail and their Analoc™ Technology to maximise signal integrity and the result is what they 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.
Complimentary 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.
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.
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.
Before the QED loom, the panellists have taken a mixed view of the various wires played to them. They’ve found positives and negatives, liked some and been lukewarm about others. But two out of the three listeners express a strong preference for this set of cables, applauding it for its clean, open, even sound that doesn’t try to do anything too clever. Instead it is very accomplished at almost every facet of the music, and makes things look rather easy.
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.
