This is an assembled GrubCableDAC. Connect it directly into any PC USB port and start listening to digital music! Native 16-bit, 44.1kHz performance requires no special drivers.
The custom cable output includes 4-wire (2 grounds), 22ga SPC teflon-insulated wire, all wrapped up in quality heat-shrink and terminating in two, high-quality, gold-plated RCA plugs. Nothing else is needed - simply plug one end into your PC's USB port and the cable end into your amplifier.
Performance is the same famous GrubDAC whose kits have sold for several years at Beezar Audio. Full details, history, specifications, and tests can be found at diyforums.org
