Stax SR-404 LE

Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $600 and $780. The full range is tight — lowest to highest is only 1.7×, 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

Ask for measured figures rather than descriptions — transconductance and hours where available. Matched pairs and quads carry a genuine premium, and matching claims should be backed by measurements from a known tester.

This range reflects 11 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is a large enough sample to price against with reasonable confidence, though condition and provenance still move individual units.
