Signature Supremus Speaker Cable, Terminated, 5M

QED Supremus loudspeaker cable is the ultimate expression of sound born of pure science.

Developed without compromise, it has been over 20 years in the making. The largest cross sectional area of pure copper ever incorporated into a QED loudspeaker cable, enables Supremus to deliver the ultra-low resistance required to ensure perfect fidelity of the musical signal. AirCore™ technology, unique to QED cables, means unrivalled high frequency detail, rhythm and timing. Supremus boasts sixteen silver plated, 99.999% oxygen free copper, solid core conductors. Each individual conductor is insulated by a nearly invisible layer of enamel, providing ultimate insulation for a more detailed output. The complete cable is then cryogenically treated to below -190 °C eliminating any dislocations in the material’s microstructure for an improved tonal performance and lower resistance signal pathway. To complete its no compromise sonic performance QED Supremus is terminated using rhodium plated Supremus Airloc™ plugs, utilising an oxygen free, cold weld connection ensuring there will be no oxidisation of the  contact surfaces and the low resistance performance will remain for the lifetime of the cable.
