This is a buyer’s market at this level: against 13 recent GBP comparables, £68 sits above the £62 75th percentile and well over the £52 median, so it reads as ambitious rather than fair. I’d only call it compelling if the box is complete, the unit is genuinely pristine, or the seller can justify the premium with original accessories and proof of light use.
The SU-1 is well-regarded because it’s a straightforward, competent DAC with a strong reputation for clean, neutral conversion and very good value when priced in the usual used bracket. If you like the model and the listing is clean, the upside is mainly convenience and low-risk ownership, but at this ask I’d still want condition, included leads, and the exact input/output spec confirmed before jumping.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
