Price trend
6 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
13 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $160 and $180. 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 13 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.
