US$150 is a strong deal against your local comparable set: it sits well below the US$160 25th percentile, far under the US$265 median, and comfortably beneath the US$347 75th percentile. That makes it a bona fide bargain rather than just a decent buy.
The D50s is well regarded as a clean, low-noise DAC with solid USB/coax/optical flexibility and a sound that stays neutral and competent in a modern system. At this price, the upside is obvious if it powers on cleanly and includes the original essentials; the main buyer checks are simply whether the unit is fully functional, the display/control behavior is normal, and the seller can confirm the condition is honest.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
