Understanding the market

Half of recorded transactions fall between $650 and $1,000. 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

Ask when the unit was last serviced and whether the output devices are original. Bias and DC offset drift with age on solid-state amps. Confirm both channels have been tested under load, not just powered on.

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.
