AirTight Announces 2024 Edition of ATM-1E Stereo Power Amplifier

"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
