25 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $3,199 and $3,500. The full range is tight — lowest to highest is only 1.4×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.
Over the last twelve months this model averaged $3,212 across 6 recorded sales, 6% higher than the preceding twelve months.
What buyers should know
Confirm the gain and loading options match your cartridge type — a moving-coil cartridge into a moving-magnet-only stage will not work. Ask whether loading is adjustable and whether any internal jumpers are documented.
This range reflects 25 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.
