Condition is unknown, so this sits on price alone, and at £245 it’s clearly ambitious versus the recent used market: the median is £152, the 75th percentile is £169, and this asks well above both. That’s not a bargain stretch; it’s a premium ask that needs a stronger-than-usual package to justify it.
The M500 is a respected DAC for clean, detailed, no-nonsense conversion, so it can absolutely be a worthwhile buy if the unit is pristine, includes the remote and original accessories, and has a solid history. But at this level, buyers should expect something exceptional—verified condition, box, accessories, or a seller with standout provenance—because otherwise the value case is weak for a used piece in this class.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
