Benchmark DAC1, black, heavily modified by Parts Connection (Chris Johnson of Sonic Frontiers and Anthem).
Classic DAC1 (no USB) which still to this day is considered a reference and many users prefer it to newer DAC2 and 3 based on Sabre and AKM chips.
Long list of enhancements below, mostly focusing on replacing 5533 opamps, replacing capacitors with Black gates, replacing resistors on output stages, new RCA connectors and fuses. The amount of mod work is non trivial considering the size of the device - see photos.
Good condition, rating of 7 due to typical wear
Universal voltage, 90-250v 50/60 hz, will work anywhere in the world.
