At A$780, this is clearly ambitious against the recent used market: it sits above the A$707 75th percentile and well above the A$602 median from 12 comparable listings. For an unknown-condition example, that premium is difficult to justify; a more compelling buy would land around the median, unless it is exceptionally clean and complete.
The A90 Discrete is well regarded for its powerful, transparent presentation, very low noise, and ability to drive demanding headphones or act as a serious preamp. It offers plenty of balanced connectivity and useful gain flexibility, so it remains a capable centerpiece for a headphone system. At this asking price, insist on confirmed working condition, clean controls and connectors, the original power supply, and ideally the box and accessories; otherwise, negotiate firmly toward typical market value.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
