QED Signature Supremus Speaker Cable 2.5M

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.
