Unknown condition makes this slightly less effortless than a pristine listing, but at £10,000 it still looks broadly fair against the recent used market, which sits around £9,770 with a fairly tight £9,678–£9,862 band. It is a touch above the 75th percentile, so I’d call it a mild premium rather than an overreach.
That premium is easy to justify if it’s complete, well cared for, and properly serviced: these are serious, big-boned monoblocks with a reputation for scale, drive, and low-level finesse, especially into revealing speakers. The upside here is the chance to buy one of Ayon’s statement amps without jumping into new-retail territory, but because tube monoblocks are heavy, costly to ship, and not cheap to refurbish, buyers should still confirm tube life, service history, and any included accessories before paying up.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
