The Matrix Audio MA-1 is the company's flagship Class AB power amplifier, engineered to deliver exceptional control, dynamic range, and musical refinement for reference-grade Hi-Fi systems. Designed to partner with the Matrix Audio M Series components, it combines substantial power output with meticulous analog engineering to drive even the most demanding loudspeakers effortlessly.

Each channel features a fully independent dual-mono design powered by its own toroidal transformer and a high-current push-pull output stage using ten ONSEMI power transistors. This architecture minimizes channel crosstalk while providing outstanding current delivery, low distortion, and excellent speaker control across a wide range of listening levels.

Delivering 250 watts per channel into 8 ohms and up to 450 watts into 4 ohms, the MA-1 offers effortless dynamics for both music and home audio applications. It can also operate in bridged mode for significantly higher output, making it suitable for driving large floorstanding loudspeakers or reference monitoring systems.

Built around a precision-machined aluminum chassis, selectable gain settings, and balanced XLR connectivity, the MA-1 is designed to integrate seamlessly into high-end audio systems. Its combination of robust power delivery, premium construction, and refined sonic performance makes it an ideal amplifier for audiophiles seeking accuracy, transparency, and long-term reliability.
