Is this one of those rare used buys where you should move first and ask questions after? At S$28,800, it lands below the S$29,558 25th percentile and well under the S$32,162 median for recent comparable listings, so this reads as a strong deal rather than merely “fair.”
That makes it attractive if the unit is genuinely like new, because this model is prized for its big, authoritative presentation, effortless dynamics, and the sort of drive that makes demanding speakers wake up. A clean example with complete accessories and verified servicing history is the kind of listing worth jumping on quickly; the upside here is mainly in rarity and condition, not in waiting for a better number.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
