10 market transactions via web search — not HiFi Registry sales.

Understanding the market

Half of recorded transactions fall between $3,199 and $4,275. The full range is tight — lowest to highest is only 1.5×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.

What buyers should know

The transport mechanism is the limiting component, and many are no longer manufactured. Ask whether the laser assembly has been replaced and whether the unit reads CD-R and recordable media, which is usually the first symptom of a tiring transport.

This range reflects 10 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is a large enough sample to price against with reasonable confidence, though condition and provenance still move individual units.
