Price trend
14 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
3 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $450 and $495. The full range is tight — lowest to highest is only 1.1×, 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 output impedance suits your headphones; a high-impedance output into low-impedance planars is a common mismatch. If tubes are fitted, establish their age and availability.
This range reflects 3 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.
