TEAC HA-507S 13,400mW Headphone Amplifier & Pre-Amplifier

The TEAC HA-507 is a high-performance analog headphone amplifier and preamplifier designed for purists who demand power, precision, and tonal fidelity. Delivering up to 13,400 mW per channel, it drives even the most demanding headphones with authority and composure. As part of TEAC’s advanced Reference 500 series, the HA-507 blends classic analog warmth with modern design, offering a balanced signal path and dual-mono architecture for exceptional channel separation. Its striking build quality, including aluminum panels and precision analog meters, reflects both craftsmanship and performance refinement in equal measure.

Inside, the HA-507 features fully discrete, dual-mono circuitry optimized for wide dynamic range and low distortion. The output stage employs TEAC’s proprietary diamond buffer configuration, ensuring stable current delivery while maintaining linearity across all impedance loads. Users can select between high and low gain modes to accommodate a wide variety of headphones—from sensitive IEMs to planar magnetics—while maintaining superb control. The front panel hosts both balanced XLR and single-ended outputs, complemented by balanced and unbalanced inputs on the rear for integration with source components. A large toroidal transformer and independent power supplies for each channel reduce crosstalk and noise, delivering a pristine signal foundation. The HA-507’s preamplifier function extends its utility to active speakers or external amplifiers, adding flexibility to its pure analog pedigree.

For serious headphone listeners and system builders, the TEAC HA-507 stands as a reference-class component that bridges precision engineering and musical soul. It reveals the subtlest microdynamics and textures while maintaining the authority and scale of a full-sized amplifier. Whether in a desktop reference setup or a dedicated listening room, the HA-507 delivers immersive, natural sound with the depth and integrity only analog design can offer.
