Understanding the market
Half of recorded transactions fall between $23 and $44. The full range runs 2.5× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
Over the last twelve months this model averaged $44 across 3 recorded sales, 83% higher than the preceding twelve months.
What buyers should know
Confirm which disc formats the unit actually plays — universal players vary considerably in SACD and DVD-Audio support. Check that firmware updates are still available, as these units depend on them more than most.
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.
