Cary Audio Design

Cary Audio Design is a company founded in May 1989 which originally designed and manufactured vacuum tube audio amplifiers. Since the mid-1990s they have expanded into the home theater market, producing DVD players and surround sound processors in addition to their original vacuum tube designs.
The company is notable as one of the few U.S. manufacturers of vacuum tube amplifiers. Many of their high-end "Classic Series" designs have received favorable reviews in audiophile publications, including "The Absolute Sound", "Stereophile" and "Soundstage!". Their CAD280 SE V12 stereo amplifier received a CES 2001 "Best of Show" designation from reviewer Jim Saxon.
Originally based in (and named after) Cary, North Carolina, Cary Audio Design's facilities are now located in the nearby town of Apex.
