Condition is unknown, so the price deserves a little verification, but at USD 550 this is clearly ambitious against the used-market evidence: the median of 467 comparable listings is USD 160, with the 75th percentile at USD 313. Unless this is an unusually complete, mint example with strong documentation and warranty coverage, it is priced well above typical territory.
The LA90 remains a very appealing compact amplifier: exceptionally quiet and transparent, with balanced inputs, Class AB operation, useful gain settings, and enough power for sensible 4- or 8-ohm speakers. It can also be used in bridged mono, though speaker-impedance requirements matter. Those strengths make it worth considering, but not at this ask without exceptional condition, accessories, and provenance. A more convincing buy would be closer to the market median.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
