McIntosh Laboratory is an American manufacturer of handcrafted high-end audio equipment headquartered in Binghamton, New York. It is a subsidiary of McIntosh Group which is under the ownership umbrella of Highlander Partners, a Dallas-based private equity firm.
The company was co-founded in 1949 by Frank H. McIntosh & Gordon Gow. McIntosh Labs designs and produces audio amplifiers, stereo tuners, loudspeakers, turntables, music streamers, processors, and various other audio products. Although solid state components are a large segment of the McIntosh line, audio enthusiasts most revere the warm sound of the company's tube amplifiers. Some of their tube amplifiers rank among the finest ever created for home audio and theater use.
