Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $2,700 and $3,500. The full range is tight — lowest to highest is only 1.3×, 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

Confirm the phono stage and headphone output work if fitted, as these are often untested by sellers. On units with digital inputs, check whether the DAC section is still supported and what sample rates it accepts.

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.
