OVERVIEW

Reference 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.

FEATURES AND BENEFITS

Engineering pedigree

QED has been designing and engineering superior analogue and digital cables for more than 45 years, and its new Reference Audio 40 cable is informed by the results of the company’s exhaustive research into cable design since 1995.

All-new Analoc2™ design

The Analoc2™ design still features low bulk, high purity copper connectors alongside low mass metal barrels, but now cleverly substitutes high rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the detrimental effects of eddy currents. Although already smaller than in traditional bulk brass plugs, these unfavourable currents were still able to circulate weakly in the isolated metal body of the previous plug design. Now with the new material in place, these remnant resonant distortions are completely prevented from adversely affecting the information contained in the audio signal as it travels through the new plug.

To complete the RCA plug’s Analoc2™ upgrade and to help combat the skin effect, the hollow, gold (or rhodium) plated, high-purity copper signal-pins are retained, while the effectiveness of the slip ring which locks in place the similarly plated, pure copper ground-terminal as the barrels are tightened, has also been improved.

Ferrite cord insulation

A Zn/Mn Ferrite jacket is used within the cordage to absorb very high frequency noise components outside of the audible band that have an adverse effect on the micro-timing of the audio signal. When measured at very high frequencies, Reference Audio 40 cables exhibit cleaner signal transmission than standard audio interconnects. Further protection for the Silver Plated 99.999% Oxygen Free Copper (SPOFC) conductors comes in the form of a low loss, low density, dielectric foam Polyethylene (LDPE) inner jacket that minimises

electrical energy loss in the cable insulation which can have a detrimental effect on the fidelity of the sound compared with cheaper PVC alternatives

PERFORMANCE

OVERALL PERFORMANCE

Analoc

Analoc2™ Technology

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. 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 detrimental effects of eddy currents.

CCT

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.

Ferrite

Ferrite Insulation Technology

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.

excellent cable!
Review First thing I noticed was how well made this cable was, it really seems worth the money, the second thing was the sound or should I say lack of it! All you hear is the sound without colouration, pristine and crystal clear. You could spend much more and get less, buy this you wont regret it, and if this is your first decent interconnect upgrade from the freebee cable supplied with a cd-player it will come as a revelation as to what you were missing!
