This is a buyer’s market only up to the mid-range here, but at A$750 it reads as ambitious versus your local comps: it’s above the A$678 75th percentile and well over the A$650 median. For this model, I’d want either stronger condition, extras, or some room to negotiate before calling it compelling.
The A90 Discrete is well-liked because it’s a clean, powerful, very low-noise headphone amp with excellent drive and a noticeably resolving, controlled presentation. If the unit is genuinely clean, original-owner, and includes the right power supply and accessories, it’s still a solid piece to own; the upside is in performance rather than novelty. At this price, though, I’d only move quickly if the condition is excellent and the package is complete.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
