Matrix Audio MA-1NS2

Technical mastery in perfection – the M Series from Matrix Audio

With the new M Series, Matrix Audio has reached a significant milestone on the path to classic high-end hi-fi systems. The series consists of the MS-1 music streamer, the MP-1 preamplifier, and the MA-1 power amplifier—a complete flagship system that embodies Matrix Audio's philosophy and sound vision at the highest level. The newly developed Matrix Design Language is also being used for the first time—a design motif that will shape future product generations of the brand.

Matrix Design: Form and function in harmony

Evaluating audiophile products based on the interplay of listening experience and visual expression has always been part of Matrix Audio's brand identity. This principle is particularly impressive in the MA-1 power amplifier: as the company's first Class AB power amplifier model, the MA-1 features a minimalist yet powerfully accentuated industrial design. Hundreds of precisely placed holes of varying depths and sizes run through the simple housing, reminiscent of rhythmic impulses – as if music were dancing through the metal.

Sound synergy: perfectly tuned in a system network

The power amplifier plays a central role in the audio system: it must deliver powerful dynamic peaks and reproduce the finest musical nuances with precision. The MA-1 has been precisely matched to the MS-1 and MP-1 components, resulting in flawless tonal balance and optimal system integration.

Multi-transistor circuit in push-pull mode

To minimize output resistance, each channel features a push-pull circuit design with 10 ONSEMI high-performance transistors operating in a highly biased state. The quiescent current consumption is an impressive 300 watts. The output power is 250 watts per channel at 8 ohms or 450 watts per channel at 4 ohms – impressive power delivery.

Flexible operating modes

• Stereo mode: Classic two-channel operation – the amplifier units reproduce the left and right channels independently of each other, guaranteeing precise stereo reproduction.
• Bridge mode: Two MA-1 power amplifiers are operated in bridge mode, which unleashes enormous power reserves – ideal for power-hungry or low-impedance speakers.
• Mono mode: Two MA-1s drive one channel each – ideal for bi-wiring or high-end speaker concepts. This enables even greater sound purity and control.

Adjustable gain

Two switchable gain stages (+30 dB / +24 dB) allow flexible combination with different preamps or speakers – an important feature for integration into demanding setups.

Superior power supply

Two independent toroidal transformers with a total output of 1250 VA supply the two channels separately. The main supply voltage is ±80 V. Each channel has 14 parallel-connected 6800 µF capacitors, giving a total capacity of 190,000 µF. The parallel design reduces the internal resistance, maintaining the current delivery capacity even with complex music signals.

Engineering meets design

The so-called H-structure forms the mechanical and thermal backbone of the MA-1. This design, developed by Matrix Audio, is based on a 20 mm thick CNC-milled aluminum carrier that holds all components and is stabilized by solid device feet. The housing creates several isolated chambers, minimizing signal interference between the modules. The left-right symmetrical arrangement of the channels emphasizes not only the tonal balance but also the visual balance.

Quiet cooling with a system

The temperature is continuously monitored by two sensors on the main heat sink. If a defined temperature limit is exceeded, a virtually silent 7.4-inch fan switches on automatically and regulates its speed dynamically. Thanks to an airflow-insulated design, there are no electronic components in the air path – this effectively prevents dust deposits and extends the service life of the electronics.

Elegance you can see and feel

The industrial design of the M series is more than just aesthetics – it embodies a new design language of dots, lines, and surfaces that runs throughout the entire series. Multi-stage CNC machining and finely tuned surface finishes give the housing a sophisticated, matte feel – an experience you can both see and feel.

An emotional sound experience

The MA-1 delivers a sound image of impressive depth, detail, and musical expressiveness. Every note becomes a narrative emotion – music is not just heard, but felt. The M Series is the result of tireless development work, precise tuning, and an uncompromising passion for perfection.

Conclusion

With the M Series, Matrix Audio presents a consistently well-thought-out high-end platform that is on par with established reference systems in terms of both sound and technology. The MA-1 power amplifier in particular impresses with its superior performance, excellent build quality, and innovative details—an audiophile statement for anyone who wants to experience music in its purest form.
