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.
