Price trend

Sold or Listed Prices

10 market transactions via web search — not HiFi Registry sales.

Understanding the market

Half of recorded transactions fall between $45 and $100. The full range runs 2.9× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.

What buyers should know

Ask for measured figures rather than descriptions — transconductance and hours where available. Matched pairs and quads carry a genuine premium, and matching claims should be backed by measurements from a known tester.

This range reflects 10 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.
