Understanding the market
Half of recorded transactions fall between $1,800 and $2,000. 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.
What buyers should know
This range reflects 20 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.
