FEATURES AND BENEFITS
Zirconia Airloc™ Design
NEW: Zirconia barrels and boots
The
exceptionally high mechanical strength of zirconia, its remarkable
resistance to scratches and general wear, and its glossily lustrous
finish, make it the ideal material for this cable’s barrels and boots.
Not only are the Supremus Zr plugs gleaming and tactile, the
electrically inert nature of zirconia also means eddy currents cannot
become established and therefore plug-induced distortion remains
vanishingly low.
Airloc™ Cold Weld System
Our high-pressure
termination process compresses the conductors and plug together,
creating a cold-welded area where conductors and plug effectively become
one. Because all the air has been removed from the joint, there can be
no oxidisation or degradation in conductivity - and that’s true for the
entire lifetime of the cable.
Rhodium-plated Locking Design
Aside
from its purely decorative properties - which are considerable -
rhodium makes the surface of the Supremus Zr connectors very smooth,
increasing the contact area and reducing resistance. Designed
specifically for Supremus Zr cable, this unique contact expansion system
securely clamps the rhodium-plated beryllium copper pins into the
speaker terminals, while at the same time increasing the contact area of
the plugs, simply by twisting the plug barrel until it is tight. And
because it’s so very hard-wearing and resistant to oxidisation, rhodium
can cope with the extra load exerted by our locking design - which
ensures a perfect, maintenance-free connection.
Aircore™ Technology
Loudspeaker
cables with large cross-sectional areas are prone to skin effect, where
high-frequency analogue music signals are forced to the outside of the
conductor, and proximity effect that disrupts current distribution.
QED’s innovative Aircore technology combines hollow tubular conductors -
to minimise the skin effect - with polyester insulation and a special
spiral construction to reduce the proximity effect. This highly
effective combination evens out current density and significantly
improves the cable's uniformity throughout the audio band.
6.2 mm² Ultra-low Resistance Conductors
Boasting
a large cross-sectional area, the ultra-low resistance, silver-plated,
oxygen-free copper conductors effectively bring the amplifier
electrically much closer to the loudspeakers, enabling it to exercise
better control over them, so the fidelity of the original music signal
can be more accurately maintained.
Cryogenic Treatment
Cryogenic
treatment improves the microstructure of the copper core by eliminating
crystalline dislocations. Numerous brass musical instruments at all
points of the frequency range have been found to produce a better, more
natural tone after deep cryogenic treatment.
