35th Anniversary USB cables are meticulously hand-crafted and are the pinnacle of Purist Audio Design's cables in luxury and sound! It is fashioned using a silver twisted pair for data and completely isolated conductors for power that are passively filtered. The 35th Anniversary USB is a 2.0 USB standard spec, perfect for use between a streamer and DAC! The default configuration is USB A to B. Additional connector types can be inquired about. Available lengths start at 1.0 M (3.3 Ft.) and increase by 0.5 M (1.6 Ft.) lengths. We do not produce USB cables longer than 5.0 M (16.4 Ft.) as anything long would affect the functionality.
