Teac HA507B Analog Headphone Amplifier
The Teac HA507B isn’t just another headphone amplifier – it’s a powerhouse of pure analog sound. Designed as a part of the TEAC Reference 500 Series, it masterfully combines advanced audio technology with an uncompromising dedication to sound quality. From its robust power supply circuit to its extensive connectivity options, this amplifier redefines what high-fidelity audio truly means.
Exceptional Power Supply for Unmatched Audio Performance
The HA-507B is equipped with a robust power supply circuit that ensures exceptional driving power and a frequency response that extends far beyond its compact appearance. The amplifier’s design is geared toward providing a rich, immersive listening experience, making it a top choice for audiophiles seeking to elevate their headphone playback system.
Balanced and Unbalanced Outputs: Versatility at Its Best
One of the standout features of the Teac HA507B is its fully balanced/dual mono configuration. It boasts four powerful amplifier elements – left, right, positive, and negative – that deliver exceptional output power. With a 6,700mW + 6,700mW (32Ω) capacity at balanced output, the HA-507B is capable of driving even the most demanding, high-impedance headphones effortlessly.
For unbalanced headphones, the amplifier employs an active-ground configuration that maintains the signal ground level at zero voltage. This setup enhances the soundstage, providing an expansive audio experience that envelops the listener.
Optimized for All Headphone Types
The Teac HA507B doesn’t discriminate – it drives all types of headphones to their maximum potential. Whether you're using balanced outputs via Neutrik XLR or 4.4mm Pentaconn, or unbalanced outputs through 6.3mm and 3.5mm jacks, the HA-507B ensures optimal sound delivery.
With three adjustable gain levels – High, Mid, and Low – you can fine-tune the amplifier to suit your headphones, achieving the perfect balance of volume and clarity.
Pure Analog Preamp Mode for Enhanced Flexibility
Beyond its capabilities as a headphone amplifier, the HA-507B doubles as a pure analog preamplifier. When paired with TEAC's Reference 500 Series power amplifiers, it forms a compact yet powerful separate amplifier system. The preamp pass-through mode lets users connect high-end external preamps, maintaining full control over gain and L/R balance functions.
Advanced Volume Control for Precise Adjustments
TEAC’s newly developed TEAC-QVCS Advanced volume control circuit takes precision to a whole new level. This ladder resistor volume control system minimizes signal degradation by maintaining the shortest signal paths. With 0.25dB increments, it offers smooth volume transitions, ensuring zero crosstalk and delivering a crystal-clear audio experience.
Impeccable Build Quality and Mechanical Design
The HA-507B is as much a visual masterpiece as it is an auditory one. Constructed with a 2.8mm thick aluminum top panel and housed in a compact A4-sized chassis, it exudes sophistication while maintaining heat dissipation efficiency. The semi-floating design, Stressless Foot, and precision-engineered knobs elevate the overall user experience, making every interaction feel premium.
