Price trend

Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $9,500 and $10,850. The full range is tight — lowest to highest is only 1.6×, 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

Confirm both monoblocks have matching service histories — a pair where only one has been serviced is effectively two different amplifiers. Check that the seller has both original cartons; these are heavy and awkward to ship safely.

This range reflects 7 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.
