QED Supremus loudspeaker cable is the ultimate expression of sound born of pure science. Developed without compromise, it has been 21 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. To deliver its no compromise sonic performance, each individual conductor is insulated by a nearly invisible layer of enamel, providing ultimate insulation for a more detailed output.
