Feeling like you are listening to live music is very important. atm-audio Class A amps are so dynamic and distortion-free that they draw you deep into the music.
J. Armengol
Our amplifiers are built entirely by hand, using only the best component brands on the market.
They are assembled in a monobloc, vibration-proof aluminium chassis, using CNC technology.
Every product is individually tested to ensure the highest sound quality.
Based on the architecture of the beehives, the dozens of vertical holes dramatically dissipate the considerable heat typical of Class A amplifiers.
Our amps stay below 50 ºC after 8 hours running.
The space optimisation allows for minimal wiring which reduces considerably the weight of our amps.
The aluminum chassis mechanised by CNC contains different compartments to avoid signal interference between circuits.
The only thing you will hear from our amps when they are on is pure music and 0 noise floor.
