Compact, Powerful and Pure
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.
Equipped with Hypex “NCOREx” Specially Tuned for TEAC.
Maximum Output Power of 170 Watts/ch, 350 Watts in BTL Mode.
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.
Fully Balanced Circuitry
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.
Circuit Design Focused on Sound Quality
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.
Buffer Amplifier Power Section with Large Toroidal Core Transformer
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.
