The Supremus Report

At QED all our cable designs are informed by our 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 we 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.

      Answer: We have yet to introduce a bi-wire version of Supremus, but doubling up two single wires would have the effect of doubling capacitance and halving inductance and resistance. It won’t affect the dissipation factor, because that is a unit-less ...
