The Audioquest Big Sur cables are the first cables in the Audioquest range which uses the improved copper quality Solid PSC+ in the conductors. These solid conductors reduce electrical and magnetic interferance between the different conductors. In all cables in this series, the left and right channels are brought together in a single jacket. So keep in mind that the connectors of the Bridges and Falls cables are necessarily quite close together and allow a maximum distance between connectors of 7cm. Audioquest Big Sur is available in RCA, 3.5mm and 3.5mm - RCA in lengths from 0.6m to 20m.
