QED Reference XT40i Speaker Wire

The QED Reference XT40i Speaker Wire with X-Tube™ Technology represents a significant upgrade for any discerning audio enthusiast seeking to unlock the full potential of their high-fidelity system. Designed to deliver a purer, more dynamic soundstage, this cable minimises signal degradation to ensure your music is reproduced with exceptional clarity and precision. Whether you are connecting a premium stereo amplifier to floor-standing speakers or fine-tuning a dedicated home cinema setup, the XT40i excels in revealing subtle details and transient response that lesser cables can mask.

At the heart of this cable lies QED’s proprietary X-Tube™ Technology, a sophisticated design that dramatically reduces both skin effect and eddy currents. By employing a hollow, air-spaced conductor geometry, high-frequency signals travel more efficiently along the surface, while unwanted interference is suppressed. This results in a remarkably low inductance and capacitance, preserving the integrity of the audio signal across the entire frequency range. The cable also features a high-purity, oxygen-free copper conductor and a robust, low-loss dielectric insulation, ensuring consistent performance and long-term reliability. With its elegant, flexible construction and gold-plated connectors, the Reference XT40i is the definitive choice for those who demand the very best from their audio investment.
