QED is proud to introduce the XT5 power cable the first of a new generation of audiophile mains cables intended to complement its award winning range of speaker cables and audio interconnects. The cable features a number of proprietary technologies applied with reference to objective scientific research and subjective evaluation to bring a functional improvement in performance.   As with any QED cable an enormous amount of attention has been paid to the materials and geometry of XT5. In a drive to minimise the degrading proximity effect created as current density accumulates in the conductors nearest to each other QED has applied the lauded X-Tube technology first developed for its award-winning range of loudspeaker cables. By more effectively regulating current flow to audio equipment the equipment is free to perform as its designers intended. The XT5 also features a ferrite-impregnated jacket – designed to shield the X-Tube conductor cores from mains derived radio frequency noise. As a result high frequency noise signals than can adversely affect the performance of audio electronics are effectively eliminated. This kind of imaginative thinking and rigorous execution is typical of QED and it means the XT5s X-Tube configuration is way beyond what any nominal competitor can offer.
