Price trend

Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $150 and $225. 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.

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 8 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.
