QED - Reference Audio 40 Interconnect – 1.0m - "NA"

Performance Audio 40i builds on the success of its predecessor, offering an even more refined and immersive listening experience. Leveraging insights from the QED Genesis Report and utilizing innovative Solid Complementary Conductors, the cable effectively separates audio signals for reduced interference and increased clarity. Engineered with a combination of oxygen-free and silver-plated copper conductors of varying diameters, this interconnect delivers greater scale and dimensionality. Complemented by a ferrite jacket and foamed polyethylene dielectric, it ensures optimal signal fidelity. Praised by industry reviewers for its transparency, dynamic response, and excellent value, the Audio 40i is an award-winning solution for audiophiles who demand high performance from their hi-fi systems.

Extend the length of your headphones so you can move freely while listening to your favorite song, podcast and more. With the Best Buy essentials 12' Headphone Extension Kit & Adapters, add 12 ft. of length to your existing 3.5 mm audio cable and connect to most of your audio devices. We’ve also included 1/4" adapters, which convert either end of the extension cable into a 1/4" connection. Backed by Best Buy, a copper spiral shield improves audio quality and reduces signal loss, while nickel-plated brass connectors and flexible PVC prevent corrosion, granting lasting durability. Lengthen your audio cords and expand their connectivity options with high-quality accessories you can trust.

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.
