Understanding the market
Half of recorded transactions fall between $88 and $180. The full range runs 3.4× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
What buyers should know
Confirm exactly what is included and that the item is compatible with your specific model, since accessories are frequently listed against the wrong generation of a product line.
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.
