QED’s entry-level sub-woofer interconnect offers a very high level of screening when compared to normal line-level interconnects, this is vital in ensuring that AC mains hum is absent from this delicate signal. The dual-balanced geometry of Qunex P-SW utilises 99.999% Oxygen Free Copper conductors and a triple shield of OFC dual braids and Aluminium Mylar foil to ensure good signal integrity, even over long cable runs. P-SW is fitted with close-tolerance Qunex phono plugs that use 24ct Gold-plated pins and connectors to minimise contact resistance and long-term oxidation.
