Pioneer QX-646
Price trend
19 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
4 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $300 and $315. 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.
What buyers should know
This range reflects 4 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. Few units of this model reach the open market, which is itself useful to know: thin trading means published prices move further on any single transaction, and it usually means less negotiating room when one does appear. Treat this as an indication of where the model trades rather than a settled valuation.
