LUXMAN 1956~1986

In the past 60 years, 30 with Luxman and 30 with Air Tight, I have been fortunate to witness the transformation of our industry. From the beginning with vacuum tube amplification to solid-state and the concept of analog playback to digital, all in the pursuit and re-creation of the musical experience.
It is a supreme honor for me to be included in The Absolute Sounds “Hall of Fame” and I will continue to contribute so long as I live, to the reproduction of high quality music. That is my promise and commitment. There is a saying in Japan, that when one reaches the age of 80, one receives an invitation from another world. And I always reply, “It is too early as I still have many tasks to achieve.”
I extend my appreciation to Messrs. Jonathan Valin, Robert Harley, and Julie Mullins for shining their light on our company by visiting and experiencing our Air Tight factory in Osaka, Japan. Thank you.

Atsushi Miura, President

  • In 1986 when the audio industry was in the midst of chaos losing its original peerless “dream” in the general shift from valves to transistors, our A & M Ltd. was founded with ardent wishes to create such products that provide full listening pleasure to all music lovers and audiophiles, thus enabling them to form an increasing attachment by repeated listening.
  • The philosophy is crystallised, through an exhaustive research and development, in the AIR-TIGHT branded audio gear featuring refined cosmetics, strictly select components, PCB-free point-to-point meticulous hand-wiring, etc.
  • The ultimate award is the infinite musicality that extends far beyond mere specifications, approaching the sublimate soundstage presentation, in full depth and width, of live performance.
  • Small as A & M is in size, we keep on giving a challenge for realisation of our grandiose “dream”. Have a startling experience to enjoy the second-to-none musicality only our time-tested valve configuration affords!
