The SMSL SU-1 has earned a strong reputation as an exceptionally capable budget DAC, and US$69 is a fair price: it sits just below the recent comparable median of US$70, comfortably within the normal used range of US$66–US$77. It is not a bargain, but it is sensibly priced if the unit is fully working and complete.
Its appeal is straightforward: clean, transparent conversion, useful USB/coaxial/optical inputs, and enough performance to serve as a serious system upgrade without spending much. The compact, simple design also makes it easy to fit into a desktop or second system. At this price, confirm that the power supply is included and that all inputs and outputs function, but there is no obvious value problem here. For a buyer wanting an inexpensive, well-regarded DAC, this is a solid buy rather than a speculative gamble.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
