Condition is unknown, so A$630 sits a touch above the A$596 median and comfortably inside the usual A$404–A$657 used range, making it a fair ask rather than a bargain. It is not cheap enough to call a steal, but it is close enough to market that a clean example can absolutely be worth buying.
The A90 Discrete is well regarded for its very low noise, huge power reserve, and neutral, tightly controlled presentation, so it suits everything from sensitive IEMs to harder-to-drive planars. If the unit is complete and functioning properly, the appeal here is straightforward: strong performance, current-generation relevance, and a price that still leaves room for a sensible negotiated win if the seller is open to it.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
