TEAC Audio AP-505 Stereo Power Amplifier - Black

TEAC Audio AP‑505

Delivers high-end power and precision in a compact footprint — the AP-505 is a fully-balanced stereo power amplifier tuned for serious audio performance.

Product Description

The TEAC Audio AP-505 is a focused stereo power amplifier designed for demanding hi-fi systems, offering class-D efficiency with refined engineering. It uses a advanced Hypex Ncore module that TEAC has individually tuned to deliver both high output and musical authority. 

Whether you’re driving floorstanding speakers or integrating into a compact system, the AP-505 offers three selectable operating modes: traditional stereo, bi-amp (separate drivers) and BTL (bridged) mono mode for extreme power. 

The chassis is designed for minimal vibration and maximum stability—with full-metal panels, “Pin-Point” isolation feet and a fan-less build to maintain silent operation even under heavy use. 

With stereo mode output rated around 130 W + 130 W into 4 Ω, and up to 250 W in bridged BTL mode (8 Ω) according to TEAC's specs, the AP-505 is quite capable for high-fidelity listening.
