TEAC- USA AP-507 Stereo Power Amplifier

The AP-507 combines compact design with remarkable power, setting a new benchmark for sound quality compared to its predecessors. Pair it with the UD-507 Discrete DAC/Preamp or the HA-507 Preamp to create a high-performance, space-saving amplifier system with a sleek “letter size” footprint. Whether installed in a dedicated audio room, a living space, or even on your desktop, the AP-507 delivers exceptional versatility and performance.
Perfect for headphone enthusiasts looking to enhance their listening experience with speakers, the AP-507 is a powerhouse in a compact form. Designed to handle even the large floorstanding speakers, it offers outstanding sound quality and seamless drivability across any speaker setup.

The AP-507 is powered by the NCOREx, a cutting-edge power amplifier module crafted by Hypex in the Netherlands and expertly tuned by TEAC. Despite its compact design, the AP-507 delivers impressive performance, with high power output of 170 watts per channel at 4 ohms and up to 350 watts at 8 ohms in BTL mode.
This next-generation NCORE module sets a new standard in audio performance, offering enhanced spatial imaging, a three-dimensional soundstage, and unparalleled clarity. Tailored specifically for the AP-507, TEAC’s custom tuning ensures it delivers the precise sound signature the brand is renowned for. The in-house developed dual-mono buffer amplifier, a critical element for achieving superior sound, has been meticulously redesigned with optimized components and circuitry to elevate sound quality beyond previous models.

The AP-507 is engineered for pristine audio clarity, utilizing fully balanced transmission across all stages of its front-end buffer amplifier and power amplifier sections. This design effectively eliminates common-mode noise, ensuring ultra-low noise signal transmission and an exceptional signal-to-noise ratio for an uncompromised listening experience.

The dual-mono buffer amplifier, a critical component for superior sound quality, has been meticulously refined for the AP-507. By re-evaluating and enhancing its parts and circuitry, TEAC has achieved even greater audio performance than previous models. Both the RCA and XLR input circuits feature the premium Muses 8820E operational amplifier, ensuring high-fidelity sound reproduction. Additionally, the XLR input section is designed without coupling capacitors, eliminating transmission loss and preserving musical detail with unparalleled accuracy and clarity.

The AP-507 features a robust power section for its buffer amplifier, anchored by a large toroidal core transformer. Its dual-mono power rectifier design, with independent left and right channels, ensures optimal channel separation and eliminates interchannel crosstalk. Each channel is equipped with 18,800 μF of capacitance to deliver powerful, clear sound. Additionally, Schottky barrier diodes are incorporated to suppress rectification noise, providing a cleaner, more stable power supply for enhanced performance across all front end sections.

The AP-507 is a versatile stereo amplifier that adapts seamlessly to your audio setup. It can be paired in bi-amp mode to independently drive the woofer and tweeter, or configured in BTL mode to deliver a powerful 350 watts into 8 ohms. This flexibility allows you to create an optimal system tailored to your specific speaker configuration, ensuring exceptional performance and sound quality.

With its compact design and impressive output power, the AP-507 is the perfect choice as a dedicated power amplifier for multichannel AV surround systems. The control terminal (Trigger In/Through) enables seamless synchronization, allowing you to power multiple AP-507 units on or off simultaneously via an AV preamp/amplifier with trigger output capability.

The AP-507 features a highly rigid chassis, crafted with aluminum front, top, and side panels encasing a solid steel frame. This robust design, combined with heavy internal components, minimizes vibration to ensure stable, high-quality performance. Its compact, letter-size footprint seamlessly complements modern interiors and can easily fit on a desk. Even when used in pairs for bi-amp or BTL mode, the AP-507’s space-saving design preserves a clean and unobstructed listening environment.

To enhance sound openness and natural sound signature, the AP-507’s 2.8mm aluminum top panel is semi-floating, sitting in place without screws, secured by slots in the side panels. This design, paired with TEAC’s proprietary Stress-Less Isolation Feet which feature a clearance between the bottom panel and the foot delivers a rich, natural sound signature.
The AP-507 is a high-performance, premium amplifier in a compact form, meticulously engineered for efficient heat dissipation without the need for exhaust fans, ensuring a quiet and immersive listening experience.
