Understanding the market
Half of recorded transactions fall between $2,352 and $2,850. The full range is tight — lowest to highest is only 1.9×, 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 $2,511 across 11 recorded sales, 5% lower than the preceding twelve months.
What buyers should know
This range reflects 32 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.
