TEAC announces AP-507 power amplifier with custom tuned new generation Hypex NCOREx module.
TEAC Custom NCOREx Redifines Compact Stereo Amplification
The AP-507 features TEAC’s own custom-tuned new generation ‘NCOREx’ power amplifier module. This advanced ‘x’ generation NCORE has been meticulously tuned by TEAC’s R&D team to achieve a unique specification tailored for exceptional audio performance. At the heart of its superior sound is TEAC’s in-house designed dual-mono buffer amplifier. Known for its ultra-linear performance, low distortion, and high efficiency, the TEAC-enhanced fully balanced design allows the AP-507 to reproduce music with remarkable fidelity, capturing every nuance and detail of the original recording.
Versatility for Every Audio Setup
The AP-507 brings big capabilities in a small footprint. This innovative amplifier is crafted for audiophiles who demand precision, clarity, and dynamic performance while fitting
Product Overview
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.
