Headlining its feature set is TEAC’s custom-tuned NCOREx power amplifier module—an evolution of the highly regarded NCORE platform, now optimised for even lower distortion, greater efficiency, and enhanced sonic fidelity.

The AP-507 is part of TEAC’s 500 Series lineup, aimed at delivering high-end performance in a space-efficient design. The standout feature is the NCOREx power module, engineered by Hypex and fine-tuned by TEAC’s R&D team. This next-gen Class D technology boasts improved transient response, lower noise floor, and a more refined output stage, which translates to a cleaner and more natural music presentation. At its core, the AP-507 employs TEAC’s proprietary dual-mono buffer amplifier, a fully balanced design that aims to maintain signal integrity across all stages. According to TEAC, the result is ultra-linear performance with minimal distortion, ensuring an accurate and detailed listening experience.

Despite its compact form, the AP-507 doesn’t hold back in terms of power delivery. It offers 170W per channel at 4Ω and up to 350W in bridged BTL mode at 8Ω, making it a viable choice for driving demanding speakers or serving as part of a bi-amp configuration. Whether deployed in a two-channel hi-fi system or as part of a home theatre setup, the AP-507’s multiple operating modes provide flexibility for various applications.

TEAC has paid close attention to mechanical integrity, incorporating a 2.8mm thick semi-floating aluminum top plate and a three-point Stress-Less Isolation Foot system to combat vibrations. The rigid chassis design aims to minimise unwanted resonance, contributing to a more open and natural soundstage. On the power supply side, the AP-507 is equipped with a high-capacity toroidal transformer and 18,800μF capacitors per channel, ensuring stable current delivery and dynamic headroom.

Unlike many high-power amplifiers that rely on active cooling, TEAC has designed the AP-507 with a fanless architecture, keeping operational noise to an absolute minimum. This makes it an appealing option for nearfield setups or quiet listening environments where background noise is a concern.

For seamless integration into existing systems, the AP-507 features both XLR and RCA inputs, accommodating a wide range of preamps and source components. It also includes trigger in/through ports for synchronised power control in multi-component setups.With its NCOREx-enhanced performance, compact footprint, and audiophile-focused design, the AP-507 looks to be a compelling choice for those seeking high-end Class D amplification in a refined package. Stay tuned for a future StereoNET’s review where we'll put the AP-507 through it's paces.

The TEAC AP-507 will be available from late March 2025, with pricing to be set at $2,199 /€1,899 EUR/£1,899.
