This $189 asking price is a strong deal in the current used market, sitting well below the median of $140 and comfortably under the 75th percentile of $291, making it an excellent value compared to the 126 recent comparable listings. While the DO100PRO is a newer generation model featuring the dual ES9039Q2M chips that replaced the older ES9038PRO in the standard DO100 Pro, its retail price of roughly $219 means this used listing offers immediate savings without the wait for a price drop.
The DO100PRO is well-regarded for its feature-packed design, delivering balanced outputs, HDMI ARC support for TVs and PS5, and Bluetooth 5.1 alongside its dual ESS DAC architecture and OPA1612 op-amps. Reviews highlight its ability to decode up to DSD 512 and PCM 768kHz with exceptional noise performance, making it a versatile hub for both computer audio and home theater. At this price, it represents a buying opportunity for enthusiasts seeking a modern, high-spec DAC with video connectivity, provided the unknown condition is verified as clean with no missing accessories.
