Ruby Anniversary Evolution, Forty years of experience across the spectrum.

The What Hi-Fi? Five Star award winning Ruby Anniversary Evolution cable is a completely new speaker cable from QED laboratories in celebration of FORTY years at the forefront of UK speaker cable design.

It utilizes QED “Aircore Technology™” in a new miniature format to bring high end cable philosophies to the budget hi-fi market.

It builds on the success of the XT Evolution and Ruby Anniversary cables with which it shares a family heritage but now incorporates increased conductor spacing to further reduce losses and distortions caused by cable capacitance.

Aircore Technology™

QED cables above 2.5mm2 cross sectional area utilize air core technology to obviate the skin effect by bundling several separately insulated smaller cores together to make up a larger CSA.

If these conductors are arranged around a hollow central core of polyethylene the self inductance exhibited by the cable can be reduced to around half that predicted by calculation.

 

Recommend for use with QED AirlocTM Plugs

QED developed AIRLOC a solder-free, airtight perfect fusion between the two metals of cable and plug.

This ‘cold weld’ method allows the cable and plug to offer the optimum signal transfer and therefore, better sound quality.

It also reduces contact resistance and ensures perfect long-term performance.

Complementary Conductor Geometry

Utilizes conductors of different diameters to carry the same audio signal.

This provides an alternative path for high frequency audio components which might otherwise become time smeared in a single audio pathway.

Ruby Anniversary EVOLUTION is a completely new speaker cable from QED laboratories in celebration of FORTY years at the forefront of UK speaker cable design.

It utilizes “Aircore Technology™” in a new miniature format to bring high end cable philosophies to the budget hi-fi market.

It builds on the success of XT Evolution and Ruby Anniversary cables with which it shares a family heritage but now incorporates increased conductor spacing to further reduce losses and distortions caused by cable capacitance.

This new geometry utilizes two conductors of different diameters to carry the same audio signal. This provides an alternative path for high frequency audio components which might otherwise become time smeared in a single audio pathway.

Aircore Technology™ is completely effective in pushing the onset of the skin effect outside of the audio band for cables of large cross –sectional area. Because great sonic benefits are gained from Ruby Anniversary Evolution’s 3mm2 CSA it is essential that the skin effect is dealt with to avoid unwanted non –linearity in the cable’s frequency response (see Bucking the Skin Effect). Because Aircore Technology also reduces the self-inductance of the cable to around half that expected of parallel conductor geometry by calculation, spacing can be increased to reduce capacitance without the extra inductance generated by this change causing audible problems in the cable performance. The use of quality dielectrics coupled with low capacitance means that the rate of energy loss in the cable (its dissipation factor) is extremely low at 0.0001 – our lowest ever figure for a speaker cable.
