Understanding the market
Half of recorded transactions fall between $4,749 and $8,299. The full range runs 2.2× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
What buyers should know
As with receivers, value tracks codec and HDMI support rather than sound quality. Confirm the processing standards supported and whether the manufacturer still issues firmware.
This range reflects 6 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.
