Understanding the market

Half of recorded transactions fall between $6,490 and $7,499. The full observed range is unusually wide — the highest recorded price is 84.0× the lowest. A spread that wide usually means the recorded sales are not strictly comparable: different configurations or finishes, units sold for parts or with cosmetic damage, or listings where the model name is shared across more than one variant. Treat the middle range as the useful signal and the extremes as outliers worth investigating before you price against them.

Over the last twelve months this model averaged $7,798 across 3 recorded sales, 72% 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 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.
