British cable specialist QED has simply launched the newest model of its Reference Audio 40 interconnect. We known as the unique Reference Audio 40 with Analoc “a formidable stereo interconnect that ushers by a high-quality sound” and awarded it a coveted five-star overview again in 2014, so that is fairly the announcement.
This up to date mid-range mannequin – QED’s Reference vary sits above the entry-level Performance Audio 40 and under the flagship Signature collection – builds on the success of the first-gen Analoc low-eddy present design by totally eradicating all conductive materials from the plug our bodies in a bid for superior transparency, timing and audio-signal integrity. It is a new improvement that QED calls Analoc2 and, in line with the agency a minimum of, it makes the Reference Audio 40 “the last word improve from finances interconnects for a cleaner, extra detailed and dynamic sonic efficiency”.
To drill down into Analoc2 just a little extra; it nonetheless options low-bulk, high-purity copper connectors alongside low-mass metallic barrels, however now it substitutes high-rigidity thermoplastic materials for each the internal assist construction and the cable pressure reduction. The objective is to get rid of the detrimental results of eddy currents which, though already smaller than in conventional bulk brass plugs have been nonetheless, says QED, capable of flow into weakly within the remoted metallic physique of the earlier plug design. Now, with the brand new materials in place, these remnant resonant distortions are apparently “fully prevented from adversely affecting the knowledge contained within the audio sign because it travels by the brand new plug”.
To finish the RCA plug’s Analoc2 improve, the hole gold- (or rhodium-) plated high-purity copper signal-pins are retained, whereas the slip ring which locks the equally plated, pure-copper ground-terminal in place (because the barrels are tightened) has additionally been uprated.
This expertise guarantees to enhance each timing and element, however, in contrast to standard analogue interconnects, Reference Audio 40 additionally makes use of two Silver-Plated 99.999% Oxygen Free Copper (SPOFC) conductors of various diameters to hold the identical audio sign. This, says QED, offers an alternate path for high-frequency audio parts which could in any other case turn out to be time-smeared in a single audio pathway.
Moreover, a Zn/Mn Ferrite jacket is used throughout the cordage to soak up very high-frequency noise parts outdoors of the audible band. The corporate says that, when measured at very excessive frequencies, Reference Audio 40 cables exhibit a cleaner sign transmission than commonplace audio interconnects.
Further safety for these SPOFC conductors comes within the type of a low-loss, low-density, dielectric foam Polyethylene (LDPE) internal jacket that goals to minimise electrical vitality loss within the cable insulation.
The QED Reference Audio 40 interconnect is offered now within the UK/Europe and within the US from December, priced £99.95/€125/$139.95 (0.6m size), £119.95/€149/$169.95 (1m size) and £149.95/€189/$209.95 (3m size), which means costs in Australia ought to begin at round AU$187.
