QEDs brand new XT40i speaker cable builds on the formidable reputation of the XT40 cable it replaces and offers a decisive step up in sound quality. This pure oxygen-free copper cable uses an evolution of QEDs established X-Tube technology to guarantee superb timing and stereo imaging and adds the brand new and highly innovative Air Gap dielectric to bring unheard-of rhythmic accuracy and musicality to a cable of this modest price. Very low DC resistance adds unrivalled frequency response to XT40is already potent audio capability. The result is a cable that advances on the class-leading standards set by its predecessor.
