The US$1,800 asking price is a fair deal for this McIntosh MA6100, sitting just above the US$1,609 median of recent comparable listings but well below the US$1,963 75th percentile. This price reflects a solid market value for a working unit in the cabinet, avoiding the US$2,000 premium seen for pristine examples while staying clear of the US$1,089 lower end for parts or repair candidates.
The MA6100 remains a beloved 70-watt vintage pre/amp from the 1970s, prized for its warm, robust sound and reliable operation when maintained. A clean, functional listing at this US$1,800 price point offers genuine buying opportunity for enthusiasts seeking a room-filling amplifier without the hunt for restoration.
