This is a buyer’s market at £285: it lands exactly on the median of recent comparable listings, so it reads as fairly priced rather than a steal or an ambitious ask. With the 25th percentile at £223 and the 75th at £396, this sits squarely in the normal used range, so I’d treat it as a sensible buy if the unit is clean and fully working.
The A90 is well regarded for low noise, transparency, and plenty of drive, making it a strong match for both sensitive IEMs and more demanding headphones. The real upside is getting a serious desktop amp with a reputation for sounding essentially out of the way, so if the condition is good and it includes the original PSU and any extras, this is an easy recommendation at this price.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
