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.

This cable is professionally terminated by QED's engineers using a dedicated Rhodium plated, locking design banana and spade plugs to ensure maximum surface contact between the plug and terminals. Utilising QED's propriety Airloc™ technology for an oxygen free, cold weld connection made for life. AIRLOC is QED's specialised loudspeaker termination method and offers the very best termination with QED speaker cables. This is a solder-free, airtight fusion between the cable and plug offering optimum signal transfer, excellent signal quality and perfect long-term performance.
QED’s AIRLOC banana and spade plugs deliver a superior performance over many plugs offered by rival manufacturers for the following reasons. Firstly, the plug is crimped around the conductors under high pressure using a special tool supplied by QED. No soldering is used and as a result the conductors are in contact with the plug 360 degrees which maximises the surface area contact. Furthermore, the banana plug itself is in contact with the binding post again at 360 degrees. The net effect of this is it maximises the signal transfer from the plug into your equipment and hence a superior performance. When bare wire is used not all the conductors are in contact with the binding post and as a result some loss occurs. Every cable is hand-crafted to the highest possible standard after which it is rigorously tested. Only then will it finally be approved by a member of the Cable Quality Team.
