HOW TO CHOOSE QED REFERENCE Audio 40 | Analogue Audio Interconnects?

REFERENCE Audio 40

REFERENCE

QED Audio 40

Award-winning interconnect now with second generation Analoc™ plug design

Representing yet another stride forward in analogue interconnect design from the original specialist cable company, this model builds on the success of the first generation Analoc™ low eddy current design by entirely removing all conductive material from the plug bodies for superior transparency, timing and audio signal integrity. The Reference Audio 40 remains the ultimate upgrade from budget interconnects for a cleaner, more detailed and dynamic sonic performance.

Analoc2™ Technology

QED Analoc2™ RCA plugs feature high-purity copper signal and ground connections supported by a new non-conductive low eddy current body. The hollow central pin eliminates the skin effect at high frequencies and the revised locking barrel design clamps the dual blade ground connection firmly to the RCA sockets for improved noise rejection. The all new Analoc2™ design cleverly substitutes high rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the distorting effects of eddy currents, which are always present in ordinary plugs where bulk brass is used instead

Complementary Conductor Technology

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.
