Understanding the market
Half of recorded transactions fall between $4,600 and $4,800. The full range is tight — lowest to highest is only 1.1×, 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 8 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is enough to establish a working range, but not enough to be precise — treat it as a guide rather than an appraisal.
