The conductors of the Empress Crown cables are unique one-crystal flat ultra purity silver ribbons. From one side of the cable to the other, there is not crystal boundary which means audio distortion is essentially zero.
The Siltech Empress Crown interconnect cables are available with RCA (SST) and XLR (Neutrik nickel) connectors.
Other connectors might be available as option. Please contact your local distributor for more details and information.
