Matrix Audio QUATTRO II

Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $499 and $599. The full range is tight — lowest to highest is only 1.5×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.

What buyers should know

Digital components depreciate on input support and format compatibility rather than condition. Confirm what the USB input accepts, whether drivers are still available for current operating systems, and whether the unit is still supported by the manufacturer.

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.
