Transparent Premium USB Cable brings unparalleled accuracy to the connection between a computer and a USB Audio DAC (Digital-to-Analog Converter). PRUSB accurately transfers the full richness and dynamic range of the music stored on your computer or media server. Four shields provide superior protection from external noise interference and internal noise interference from computer power supplies. Custom, gold-plated USB connectors and precision termination techniques insure accurate digital signal transfer. The extra large gauge solid core conductors have greater surface area than typical USB cables — a quality feature that further aids digital signal transfer even over longer lengths. Transparent Premium USB Cable has extruded foam polyethylene dielectric, a far superior insulator than the material used in typical USB cables in terms of maintaining ideal propagation speed and reducing signal loss.
