Price trend
9 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
10 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $2,250 and $2,649. The full range runs 2.3× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
What buyers should know
Confirm the unit is rated for your mains voltage and that the surge protection components have not already absorbed a fault — many conditioners continue to pass power after their protection stage has been spent.
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.
