At US$250, this sits right on the median of the recent used market and matches the going typical price rather than asking a premium. With comps spanning US$225–US$275, it reads as a fair buy, not a bargain and not overpriced.
That works in this case because the D30 Pro is a well-liked DAC for clean, low-noise conversion, balanced output support, and generally “set it and forget it” reliability in a desktop or headphone rig. If the unit is clean, fully functional, and includes the original power supply and remote, this is a sensible pickup; at this price, the main value is solid performance without paying new-gear money.
