Sold or Listed Prices
18 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $449 and $750. The full observed range is unusually wide — the highest recorded price is 63.3× the lowest. A spread that wide usually means the recorded sales are not strictly comparable: different configurations or finishes, units sold for parts or with cosmetic damage, or listings where the model name is shared across more than one variant. Treat the middle range as the useful signal and the extremes as outliers worth investigating before you price against them.
Over the last twelve months this model averaged $611 across 3 recorded sales, 71% higher than the preceding twelve months.
What buyers should know
Ask for measured figures rather than descriptions — transconductance and hours where available. Matched pairs and quads carry a genuine premium, and matching claims should be backed by measurements from a known tester.
This range reflects 18 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is a large enough sample to price against with reasonable confidence, though condition and provenance still move individual units.
