QED Signature Supremus Loudspeaker Cable Pair 2.5m Overview
The QED Supremus Speaker Cable sets a new standard for excellence, delivering a truly extraordinary listening experience that will leave audiophiles and music enthusiasts alike in awe. The cable is meticulously crafted, with each individual conductor insulated by a layer of enamel, providing ultimate insulation and ensuring optimal signal integrity and features the largest cross-sectional area of all QED speaker cables. This attention to detail ensures that your music flows through the cable with unparalleled purity and precision. Supremus undergoes a cryogenic treatment during manufacturing, which eliminates material fractures and imperfections. This treatment enhances the tonal balance and overall performance of the cable, resulting in a smoother and more refined sound – a process often performed on high-quality brass instruments such as trumpets to improve sonic performance. At the core of the QED Supremus Speaker Cable lies Aircore™ Technology, a ground breaking feature that utilizes a hollow insulating centre tube. This innovative design optimizes signal-contact and distribution, allowing your music to breathe and come alive with unparalleled clarity and dynamics.

Full Description
View Full DescriptionQED cable designs are informed by their exhaustive ongoing research into cable parameters which began in 1995 and is detailed variously in the Genesis Reports. These reports set out the design-principles to which they have since adhered and which have resulted most recently in the development of QED Supremus loudspeaker cable, the ultimate expression of sound through science without compromise.
QED Supremus benefits from the appliance of Aircore Technology and therefore boasts very low impedance across the audio band. Cable capacitance and inductance are controlled by the use of low loss dielectrics and the unique constraints of the Aircore geometry.
At just 5 mΩ/m QED Supremus has an extremely low DC loop resistance because it uses 6.16 mm² of cryogenically treated silver plated 99.999% oxygen free copper conductors, the largest cross-sectional area cable ever to be available from QED. This brings the amplifier electrically much closer to the loudspeakers enabling it to exercise better control over them, so that fidelity to the original music signal can be more accurately maintained.
Handmade In The UK
Supremus loudspeaker cables have a complex geometry and require special machinery to prepare the enameled conductors for termination. Because of this they are handmade at QED’s facility in Woking, UK.
When ordering please specify if you require Rhodium plated locking Airloc Banana Plugs or Spades. Custom lengths can be special ordered please contact us for further details.
Cryogenic Treatment
The improvement in physical properties of copper when cryogenically treated results from the elimination of dislocations in the material’s microstructure. Trumpets and other brass instruments have been found to produce a better tone after Deep Cryogenic Treatment and it is also used to treat guitar and piano strings.
QED Aircore Technology
Aircore Technology keeps inductance and capacitance at vanishly low levels. This changes the magnetic field within the cable to ensure high frequencies travel through the central part of the conductors. The result is an unrivalled level of high frequency detail and cable timing.
6.2mm² Cross Sectional Area
Boasting two bundles of 16 Silver plated, cryogenically treated oxygen free copper conductors for ultra-low resistance exerting beautiful control, bringing your amplifier and speaker electrically closer together.
Enamelled Conductor Insulation
The conductors are uniquely individually insulated by a nearly invisible layer of enamel. This material was chosen because it has extremely good insulating properties and sets new standards in the insulation hierarchy.
