At US$42, this looks like a strong bargain versus the recent used market: it lands well below the US$70 25th percentile and far under the US$134 median. For a small desktop DAC/headphone amp, that is squarely in “buy it if it’s working” territory.
This model is popular because it combines a simple USB-free S/PDIF DAC path with a basic headphone amp in a compact, easy-to-place box, which makes it handy for secondary systems, TVs, or older digital sources. At this price, the main upside is straightforward value; just confirm it powers up cleanly and that the optical/coax inputs and headphone output are functioning, since an otherwise healthy unit here is hard to overpay for.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
