Understanding the market
Half of recorded transactions fall between $4,213 and $7,750. The full range runs 2.8× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
Over the last twelve months this model averaged $7,433 across 11 recorded sales, 28% higher than the preceding twelve months.
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 21 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.
