Flagship headphone amplifier from Trilogy quite wonderful can demonstrate, original packaging and book ,
Should you jump on a £950 asking price for a well-kept Trilogy 933? Yes — against your own comps, that sits below the £1,041 25th percentile, so it reads as a strong deal rather than merely fair. It is also comfortably under the £1,496 median, which gives the buyer a nice margin versus the recent used market.
That makes it attractive because these Trilogy headphone amps are respected for a refined, grown-up presentation: clean drive, good control, and the sort of musicality that rewards better headphones rather than just getting loud. An excellent-condition example at this level is the sort of listing I’d expect fellow enthusiasts to move on quickly, especially if it’s been cared for and includes the original packaging, manual, or PSU if applicable.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
