McIntosh MC275 Mk III (1995–2003)
The MC275 Mk III is the third version of McIntosh's tube-powered stereo amplifier, produced only from 1995 to 2003. The original MC275, first produced in 1961, is considered by many the greatest tube amplifier ever made. The Mk III carried that lineage into the modern era. One Czech listing called it a "legendary tube power amplifier."
The Mk III is built with a combination of point-to-point wiring and circuit boards, which puts it between older and newer manufacturing approaches. It has both XLR balanced inputs and high-quality RCA inputs.
Documentation on the Mk III is thin. Most of what's recorded comes from sales listings rather than period reviews or service literature. No power output specifications, frequency response, or distortion figures for this version have surfaced in the research, and dimensions and weight aren't documented either. The listings that do exist describe units in mint or pristine condition, often with original packaging, with sale prices from roughly $4,000 to £7,700 depending on market and condition. One New Old Stock example was described as a "Collectors Dream Piece."
