Overview

AT-HA5050H is a reference headphone amplifier that is designed to work with any headphones, not just those from Audio-Technica. We understand that all headphones have a distinct sound signature and can perform very differently when paired with an amp.

We wanted to make headphones perform at their best, while also letting the user choose the sound they like. So we have provided different output choices that can easily alter the sonic characteristics and performance of the headphones.

Unlike previously released headphone amplifiers, the suffix “H” in the model name signifies that AT-HA5050H is a Hybrid amplifier that employs a pair of tubes at the preamp stage and transistors at the power amp stage.

Employing tubes in the preamp adds warmth and depth to the music, while its bipolar transistors provide distortion-free Class A amplification that is powerful enough to drive any headphones, irrespective of their impedance level.
