Hello, Interest check! Who wants a beautiful Audio-GD Reference 1 DAC? This thing is a monolithic beauty. The Reference 1 is in immaculate condition physically and fully functional, no issues. Very resolving, all the details throughout the sonic range are resolved with this wonderful DAC. It includes 8 pieces of the PCM1704UK famed D/A converter which apparently is no longer in production. This is a great price for a truly high fidelity DAC. Let me know if you're interested! Picture is of the Reference 1 DAC with the Digital Interface and PSU unit on stop (not included).
