Boston Acoustics Avidea 770

Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $155 and $350. The full range runs 2.8× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.

What buyers should know

Depreciation here is driven by HDMI and codec support, not sound quality — a unit two standards behind current loses value quickly regardless of condition. Confirm the HDMI board is functional, since it is the most common failure point.

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.
