Understanding the market
Half of recorded transactions fall between $250 and $300. The full range runs 2.7× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
What buyers should know
This range reflects 5 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.
