More Information


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 XT5’s X-Tube configuration is way beyond what any nominal competitor can offer.


Without the XT5 cable to feed it with clean noise-free current, any amplifier will sound glassy and hard with less ability to respond to musical transients, giving a lack of dynamics and weak bass performance. With a clean input current, wrapped in a blanket of radio silence, any haze introduced into the upper detail of the music is removed, giving more air and life to the final musical presentation.
Finally, with the quality assurance of a fully type-tested design, QED XT5 Power Cable can be relied upon to safely bring audible improvements to the sound of both source equipment and audiophile amplification components alike.
