Sold or Listed Prices
8 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $34 and $39. The full range is tight — lowest to highest is only 1.9×, 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 $39 across 4 recorded sales, 15% higher than the preceding twelve months.
What buyers should know
Confirm exactly what is included and that the item is compatible with your specific model, since accessories are frequently listed against the wrong generation of a product line.
This range reflects 8 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.
