16 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
4 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $1,595 and $2,500. The full range is tight — lowest to highest is only 1.7×, 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 4 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. Few units of this model reach the open market, which is itself useful to know: thin trading means published prices move further on any single transaction, and it usually means less negotiating room when one does appear. Treat this as an indication of where the model trades rather than a settled valuation.
