QED XT40i (3.0m)

By increasing the separation of the conductors inside the cable, and therefore the amount of air between them, QED has created a low-loss air gap dielectric. This technology halves the dissipation and capacitance characteristics of the cable, resulting in numerous audible improvements, particularly in timing and rhythmic accuracy. Despite this increased separation, the XT40i retains a cross-sectional area that makes it ideal for long cable runs. Forming the cable conductors into a tube-like shape around a hollow insulating rod in the center of the cable equalizes current densities, delivers very low inductance, and presents a consistent, even load to an amplifier. The result is a cable that retains more of the finest musical details, handles rhythms and tempos in the most natural and musically satisfying way, and outperforms rival designs costing far more.
