Air Tight

AirTight is the brand name of A&M Limited, a Japanese manufacturer founded in 1986 by Atsushi Miura, a thirty year veteran of Luxman, together with co founder and chief designer Masami Ishiguro. Based in Takatsuki, Osaka, the company builds its preamplifiers, power amplifiers, and phono products using PCB free, point to point hand wiring and carefully selected components, refining the same flagship circuits across decades of small batch production. AirTight's founder Atsushi Miura was inducted into The Absolute Sound's High End Audio Hall of Fame in 2016, recognition that reflects the brand's standing among collectors and reviewers worldwide.
