TEAC AP-507 Stereo Power Amplifier
Description
The TEAC AP-507 Stereo Power Amplifier brings flagship-level performance to TEAC's acclaimed Reference 500 Series. Featuring TEAC's custom-tuned Hypex NCOREx® amplifier module, a fully balanced circuit design, and a robust dual-mono architecture, the AP-507 delivers exceptional clarity, dynamic power, and effortless control. Whether used in a traditional stereo system, bi-amp configuration, or bridged mono setup, it offers remarkable flexibility and audiophile-grade performance in a compact A4-sized chassis.

Key Features
Next-Generation Hypex NCOREx® Amplification
The AP-507 is powered by TEAC's custom-tuned Hypex NCOREx® Class-D amplifier module, delivering greater transparency, improved spatial imaging, and exceptional musical detail. With up to 170 watts per channel into 4 ohms and 350 watts in bridged (BTL) mode, it easily drives demanding loudspeakers while maintaining remarkable efficiency.

Flexible Stereo, Bi-Amp & BTL Modes
Designed to grow with your system, the AP-507 supports standard stereo operation, bi-amplification for compatible speakers, and high-power bridged mono mode. This flexibility makes it equally suited for dedicated two-channel systems and premium home theater applications.

Fully Balanced Audio Circuit
A fully balanced signal path, from input to output, minimizes noise while preserving musical accuracy. TEAC's proprietary dual-mono buffer amplifier further enhances channel separation, low distortion, and dynamic performance.
High-Capacity Linear Power Supply
A large toroidal transformer and oversized power supply capacitors provide stable current delivery, allowing the AP-507 to reproduce demanding musical passages with confidence, control, and authority.
Premium Mechanical Construction
The AP-507 features a rigid aluminum and steel chassis, a semi-floating aluminum top plate, and TEAC's innovative 3-point Stress-Less Isolation Foot system to minimize vibration and preserve sonic accuracy.
Silent Fanless Operation
Efficient Class-D amplification and passive cooling eliminate the need for cooling fans, ensuring whisper-quiet operation even during extended listening sessions.
RockOnAV Expert Insight
The AP-507 is a significant evolution of TEAC's compact power amplifier design. The move to the latest NCOREx® technology provides greater refinement, improved dynamics, and a more spacious soundstage while retaining the compact footprint that has made the Reference 500 Series so popular. It's an outstanding choice for audiophiles building a premium two-channel system or for anyone looking to add powerful, high-quality amplification without sacrificing valuable space.
