20 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
5 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $999 and $1,799. The full range is tight — lowest to highest is only 1.8×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.
Over the last twelve months this model averaged $1,225 across 4 recorded sales, 32% lower than the preceding twelve months.
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 5 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.
