Price trend
8 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
6 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $200 and $285. The full range runs 3.0× 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 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.
