QED cable designs are informed by their exhaustive ongoing research into cable parameters which began in 1995 & is detailed variously in the Genesis Reports. These reports set out the design-principles to which they have since adhered & which have resulted most recently in the development of QED Supremus loudspeaker cable the ultimate expression of sound through science without compromise. QED Supremus benefits from the appliance of Aircore Technology & therefore boasts very low impedance across the audio b&. Cable capacitance & inductance are controlled by the use of low loss dielectrics & the unique constraints of the Aircore geometry.
