Teac
TEAC AP-505B Stereo Power Amplifier
Best compact amplifier for discerning audiophiles seeking refined sound.
The TEAC AP-505B is an ultra-compact stereo power amplifier featuring Hypex Ncore technology, designed for high-precision musical dynamics and bi-amping capabilities. It offers versatile operation in stereo, bi-amp, and BTL modes, delivering up to 130W per channel in stereo or 250W in BTL mode. Its robust, full-metal construction with an A4-sized footprint ensures rigidity and elegance, fitting seamlessly into modern interiors. The fully-balanced design and carefully selected components, including an oversized toroidal power transformer and MUSES8820E op-amps, contribute to extremely low distortion and an excellent signal-to-noise ratio. Unique 'Pin-Point' feet minimize vibrations, enhancing the soundstage and sonic detail, while the passive-cooling design ensures silent operation. Dual analog level meters provide visual feedback on signal levels.

Know before you buy
Hypex Ncore technology is highly regarded for its efficiency and ability to deliver high-precision musical dynamics with extremely low distortion. By tuning this technology, TEAC ensures the AP-505B provides a clean, transparent soundstage that remains accurate even at higher volumes.
Yes, the AP-505B supports bi-amping, which allows you to dedicate the amplifier's power more effectively to your speakers' high and low-frequency drivers. This setup can improve clarity and separation in your audio performance.
BTL (Bridge-Tied Load) mode combines the two channels into a single, more powerful mono channel. This increases the output to 250W at 8Ω, providing significantly more headroom and driving power for demanding speakers.
Yes, the AP-505B utilizes a passive-cooling design, meaning it does not require noisy internal fans. This makes it an excellent choice for quiet listening environments where you want to avoid any mechanical background noise.
With its compact A4-sized footprint and height of just 3.3 inches, the AP-505B is designed to fit easily into modern, space-constrained setups. Its robust, full-metal construction also ensures it remains stable and vibration-free on most surfaces.
The analog level meters provide real-time visual feedback on your signal levels. Beyond their functional utility, they add a classic, tactile aesthetic to the amplifier that complements its high-end audio performance.
