Small but Mighty: TEAC Unveils the Reference 500 Series AP-507 Power Amplifier

TEAC Corporation has announced the addition of the AP-507 stereo power amplifier to its prestigious Reference 500 series. This refined new component is scheduled to reach retailers by late spring 2025.

The AP-507 represents the newest addition to the Reference 500 series—a stereo power amplifier with an elegant "letter-sized" form factor that exemplifies TEAC's commitment to sophisticated yet compact high-fidelity audio components. Boasting exceptional driving capability and wide-ranging speaker compatibility, the AP-507 excels as a standalone stereo amplifier while offering remarkable versatility. Audiophiles can select between "Dual Mono" configuration or engage the "High-Power BTL Mode" to deliver an impressive 350W into 8 ohms, providing extraordinary driving authority when needed. Despite its compact dimensions, the AP-507's flexibility makes it equally suitable for elevating the performance of AV surround sound systems, embodying TEAC's philosophy of refined engineering in a versatile package.

The AP-507 features TEAC's proprietary next-generation "NCOREx®" power amplification modules, meticulously tuned by TEAC's engineering team and manufactured by Dutch specialist Hypex. These modules implement an advanced "x" version of the acclaimed NCORE technology, delivering sound reproduction with enhanced presence, more precise three-dimensional imaging, and expansive spatial characteristics. TEAC's development team has crafted dedicated dual mono buffer amplifiers specifically for this model, and through painstaking refinement of every circuit component and design element, they've achieved an exceptional balance of crystalline resolution and musical richness that represents a new pinnacle in TEAC's audio engineering heritage.

The AP-507 is housed in a robust metal chassis featuring a 2.8mm thick semi-floating aluminum top plate. TEAC's patented three-point "Stress-Less Isolation Foot" system provides crucial mechanical grounding, with each element precisely engineered to minimize vibration transfer. This meticulous attention to the mechanical aspects of amplifier design yields audible benefits in sonic performance, allowing the AP-507 to render music with exceptional naturalness and a more expansive, unrestrained soundstage.
