TEAC Corporation (TOKYO: 6803) is proud to announce the HA-507, a Reference 500 Series pure analog headphone amplifier/preamplifier that incorporates TEAC's premium audio technologies to achieve the highest level of sound quality.

Equipped with an extensive power supply circuit, the HA-507 has exceptional headphone driving power and an extremely wide frequency response that cannot be imagined from its compact appearance. When connected to the TRDD 5 discrete DAC, model UD-507, you can create a special headphone playback system with separate digital and analog sections.

 

The HA-507 is a no-compromise headphone amplifier that can also be used as a pure analog preamplifier. When paired with a Reference 500 Series power amplifier, you can create a compact yet full-featured separate amplifier system that further enhances the quality of your loudspeaker listening experience.
