"After launch of the original “ATM-1” in 1986 and
“ATM-1s” in 2006, the EL-34 push-pull amplifier” has
been updated for the first time in 18 years as “ATM-1
(2024 edition)”. While following the orthodox yet
sophisticated design of the original model and the concept
of “a tool for listening to music”, we selected the best
parts currently available and designed an amplifier that
allows the EL-34 to provide more stable performance.
The appearance of “ATM-1 2024 edition” resembles the
original ATM-1 design, but we have made modern
updates and paid attention to every details throughout.
The main chassis is a monocoque construction that
combines strength and acoustic benefits. The exterior has
been designed to prevent screw heads exposure, and a
thick aluminum front panel is mounted as the face of the
amplifier. The bottom plate is made of bright copper
plated steel.
The amplifier is made to compact in size to appeal the
slim modern EL-34 shape while feeling sense of weight
and has a dignified sharpness, inheriting the
"AitTightness" that has existed since the company's
founding". - AirTight
