Detailed Description
Complementary Conductor Technology™
The QED Signature Audio 40 incorporates Complementary Conductor Technology™, which uses two conductors of varying diameters to transmit the same audio signal. This innovative approach provides an alternative path for high-frequency components, significantly reducing time smear and ensuring precise and detailed sound reproduction.
Teflon Dielectric
Utilizing a Teflon dielectric with its low dielectric constant, this cable minimizes signal energy loss caused by capacitance. This technology ensures that more of the original audio signal is retained, enhancing clarity and overall audio fidelity.
Cryogenic Treatment
Undergoing deep cryogenic treatment below -190°C (-310°F), the cable's material structure is refined to remove microstructural flaws. This process improves tonal quality and extends the cable's lifespan, making it a reliable choice for high-performance audio systems.
Analoc2™ Connector Design
QED's redesigned Analoc2™ connectors feature high-purity copper signal and ground connections, supported by a low-mass thermoplastic structure. This design eliminates the detrimental effects of eddy currents and resonant distortions while retaining rhodium-plated, hollow signal pins to counteract the skin effect. The improved locking mechanism enhances signal integrity and noise rejection.
