At £53, this is right on the used-market middle for a SMSL SU-1, so it’s a fair buy rather than a bargain or an overreach. With the 25th percentile at £49 and the 75th at £58, the ask sits comfortably in the normal range for this DAC.
That makes it a sensible pick if you want a compact, well-liked budget DAC that’s earned a reputation for clean, neutral sound and easy system-matching. The real upside here is straightforward: if the unit is tidy and comes with the original bits, you’re paying a market-rate price for a model that punches above its weight. At this level, condition and included accessories matter more than hunting for a huge discount.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
