|The groundbreaking Signature Audio 40 analogue audio interconnect celebrates QED's 40 years at the forefront of British designed audio cables.
Signature Audio 40 is an entirely new design concept from QED laboratories. The cordage is designed primarily for low capacitance as this has been identified by QED as a significant factor leading to a high fidelity experience and makes for a tight sound retaining the rhythm of the original piece. Add There Complementary Conductor TechnologyTM for high frequency detail and there Analoc TechnologyTM to maximise signal integrity and the result is what we they 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.
Complementary Conductor TechnologyTM
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.
This material with its low dielectric constant has been used to cut down on the amount of audio signal energy lost due to cable capacitance.
It is understood that cryogenic treatment results in the elimination of dislocations and fractures in the material’s micro-structure. Trumpets and other brass instruments have been found to produce a better tone after Deep Cryogenic Treatment and it also extends their working life. Our extensive listening tests have shown that the cryogenically treated cable is preferred over the same cable without the treatment.
ANALOCTM 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.
"Here’s a genuinely impressive sounding audio interconnect. Although not completely translucent, the new Signature is open and detailed like few others at the price, with a light, spry sort of sound that captures the energy of the music in its full glory. Tonally, it’s very close to neutral, but comes across as just a little ‘well lit’ in absolute terms, pepping up otherwise lacklustre recordings or systems by a fraction. It has strong and taut bass, happily lacking in overhang or smear, and a crisp and incisive midband that lets the elements in the mix hang in their respective positions in space with ease. It doesn’t crowd out things, offering a nice spacious soundstage where there’s room for the music to breathe. Treble is sweet and airy, too. Overall then, this new cable is an excellent performer at the price, right across the board." HiFi Choice Recommended March 2014

We are pleased to offer a free cable burn-in service for this cable when purchased through us. The Nordost VIDAR cable burn-in machine combines three different functions all in one operation:
- It neutralises charges that build up around the cables and the insulation
- It provides a very wide band and deep conditioning into the conductor core, which produces changes in the way signals pass through the metal.
- It ultrasonically conditions the surface of the conductors.
The VIDAR uses a proprietary combination of composite and complex signals to condition the cables. Parts of the signal oscillate at ultra-low frequencies, while other parts are in ultra-high ranges which extend beyond the range of video frequencies. The signal bounces in a ping-ping ball-like fashion from one end of the cable to the other. During the burn-in process, ultra-low frequencies penetrate deep into the core of the cable. The ultra-high frequencies zip along the surface. This method of signal transmission a set up beat harmonics, or heterodynes, between the two complex waveforms. In the digital domain, this would be referred to as aliasing products. These beat frequencies penetrate all layers of the cable.
The design of the circuitry also has a unique feature which drives electrons above the conductor into the dielectric (or insulation) area. The VIDAR not only sends ping pong signals along the cable, it also sends a similar signal from the centre core to the outer shield in the case of interconnect cables. This function neutralises the electrical charges discussed above.
So what does that all mean to me?
The end result of conditioning cables with the Nordost VIDAR is improved sound staging, increased detail, and an overall more musical presentation.
