This is slightly above fair value rather than a bargain. With recent comps centered at £52 and the upper quartile at £59, the £62 ask sits just over the typical market band, so it’s a touch ambitious but not out of line for a clean example.
What makes it worthwhile is that the SU-1 is a well-liked little DAC: compact, straightforward, and generally respected for giving you a clear, competent digital front end without fuss. If the unit is complete and in tidy condition, the extra few quid over median is easy to justify; I’d mainly want confirmation that it powers up cleanly and includes the essentials, since at this price you’re paying for convenience and condition as much as the hardware itself.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
