Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $140 and $165. The full range runs 3.2× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.

Over the last twelve months this model averaged $166 across 4 recorded sales, 9% lower than the preceding twelve months.

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 9 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.
