Octave Audio HP 500 SE

Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $5,000 and $6,500. The full range runs 2.7× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.

What buyers should know

Check whether the unit uses tubes or solid-state gain, and if tubes, when they were last replaced. Confirm all inputs switch cleanly and the volume control is free of channel imbalance at low levels, which is the most common wear point.

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.
