Understanding the market

Half of recorded transactions fall between $1,648 and $1,999. 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 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.
