About this product
The groundbreaking Signature Audio 40 analogue audio interconnect celebrates QED's 40 years at the forefront of British designed audio cables. Signature Audio 40 is a completely new design concept from QED laboratories, developed with low capacitance cordage to preserve high-fidelity audio. The innovative Complementary Conductor Technology™ ensures high-frequency detail is retained, while the Analoc2™ connector design enhances signal integrity by eliminating distortions caused by eddy currents. Additional features include cryogenic treatment of the cable to enhance tonal quality, a Teflon dielectric to reduce capacitance-induced signal loss, and a rhodium-plated, high-purity copper connector for long-term contact reliability. The cable's geometry and shielding also ensure electromagnetic noise rejection, making this one of the most advanced interconnects QED has ever produced. The Signature Audio 40 offers premium materials and performance, combining science-backed engineering with audiophile-grade components to enhance any high-end audio system.
