HA-507
Pure Analog Headphone Amplifier / Preamplifier to Further Expand the World of Headphone / Speaker Listening
The HA-507 is a 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.


A layout for exhibition is shown. Install each unit on the audio shelf individually, when perform.
As an authentic pure analog
headphone amplifier
Combined with your favorite DAC or digital player, you can build a full-fledged headphone listening system.
As a compact
premium preamplifier
Combined with the Reference 500 series power amplifier, a compact separate amplifier system with authentic sound quality can be realized.
* Shown with the AP-505 which has been discontinued. A successor model is scheduled.
… And,
as a “headphone power amplifier”
If you already have a higher quality preamplifier in your speaker system, you can pass through the HA-507’s preamplifier and add it as a “headphone power amplifier”.
