At A$650, this is above the median A$440 and also above the 75th percentile A$659 only by a hair on the supplied comps, so it reads as slightly ambitious rather than a clear bargain. For a used cable, I’d want the listing to justify that with excellent condition, provenance, and complete termination details; otherwise, the market anchor suggests there’s some premium baked in.
That said, Vertere’s cable range is generally well regarded for low noise, good timing, and a clean, open presentation, so the right system can absolutely benefit. If it’s genuinely tidy and from a careful owner, the upside is a high-end cable at a still-credible used level; I’d mainly be checking connector wear, length, and whether both ends are exactly what you need before paying the full ask.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
