QED XT40i (3.0m)

By increasing the distance between the conductors inside the cable and thus the air volume between them, QED has created a low-loss air-gap dielectric. This technology halves the loss and capacitance characteristics of the cable, leading to numerous audible improvements, particularly in terms of timing and rhythmic accuracy. Despite this increased spacing, the XT40i maintains a cross-sectional area that makes it ideal for long cable runs. The shaping of the cable conductors into a tubular structure around a hollow insulating core in the center of the cable equalizes current densities, delivers very low inductance, and provides a consistent, even load for an amplifier. The result is a cable that preserves more of the finest musical details, handles rhythms and tempos in the most natural and musically satisfying way, and surpasses competing designs that cost significantly more.
