23 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
11 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $125 and $180. The full range is tight — lowest to highest is only 1.9×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.
Prices over the last twelve months have held roughly flat, averaging $150 across 3 recorded sales.
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 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.
