QED Reference Audio 40 RCA Cable Red 3M

QED Reference Audio 40 RCA Cable 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 Technology™ for high frequency detail and our Analoc Technology™ to maximize 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. FEATURES AND BENEFITS Complementary Conductor Technology™ This innovation utilizes 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. 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 is claimed to reduce inductance. Sound Quality Before the QED loom, the panelists have taken a mixed view of the various wires played to them. They have 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 does not try to do anything too clever. Instead, it is very accomplished at almost every facet of the music, and makes things look rather easy. Reference and Signature Audio40 analogue cables use 'Analoc™' plugs with a built-in locking feature so that as the barrel is screwed up tight, the clamping force is increased making for a super noise free and secure connection. To correctly fit 'Analoc™' plugs, the outer locking cylinder of the plug must be screwed forward, to loosen the gripping 'blades', whilst the plug is pushed into place on the socket. The locking cylinder should then be screwed back to lock the plug onto the socket. Users must always remember to do this when connecting/disconnecting the cables. 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.
