The Audio-Technica AT-HA22TUBE Headphone Amplifier features two vacuum tubes in the pre-amplifier for a rich, thick sound. Independent Left and Right circuits ensure high-resolution audio. Its hybrid design integrates vacuum tubes with semiconductor technology. The die-cast aluminium case reduces vibration and distortion. A line-through output supports AV systems, and the front panel offers Ø6.3mm and Ø3.5mm stereo jacks for dual headphone use.
