Understanding the market

Half of recorded transactions fall between $300 and $395. The full observed range is unusually wide — the highest recorded price is 4.4× the lowest. A spread that wide usually means the recorded sales are not strictly comparable: different configurations or finishes, units sold for parts or with cosmetic damage, or listings where the model name is shared across more than one variant. Treat the middle range as the useful signal and the extremes as outliers worth investigating before you price against them.

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.
