Understanding the market
Half of recorded transactions fall between $199 and $300. The full range runs 2.5× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
What buyers should know
This range reflects 11 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.
