Matrix Audio MA-1 – Flagship Hi-Fi Power Amplifier Perfect Creation The Matrix Audio M Series represents a major milestone in the brand’s journey towards traditional high-end Hi-Fi systems. At its core is the MA-1 power amplifier, designed to complement the MS-1 music streamer and MP-1 preamplifier. Together, they form Matrix Audio’s complete flagship system—an uncompromising showcase of design, craftsmanship, and sonic performance. Matrix Design – Audio as Art At Matrix Audio, every product is developed with equal emphasis on listening and looking. The MA-1 power amplifier introduces the brand-new Matrix Design language, where minimalism meets precision. Its elegant industrial form reflects rhythm, balance, and refined craftsmanship, setting the stage for both performance and aesthetics. Complement Each Other – The Backbone of Hi-Fi The power amplifier is the backbone of any Hi-Fi system. It must deliver explosive dynamics in demanding passages while revealing delicate subtleties with finesse. The MA-1 is finely tuned to work in harmony with the MS-1 and MP-1, ensuring perfect synergy, seamless control, and an exceptional listening experience across all genres of music. Multi-Triode Parallel Push-Pull Output To achieve high power with low impedance, the MA-1 employs 10 ONSEMI high-power transistors per channel in a push-pull Class A/B configuration operating at high bias current. With static power consumption reaching 300W: Stereo Mode – Each amplifier unit handles left and right channels independently, delivering precise stereo reproduction. Bridged Mode – Two amplifiers combine for massive power output, effortlessly driving demanding speakers with low sensitivity. Mono Mode – Two amplifiers per channel deliver extreme sound quality, ideal for bi-wiring or driving high-end separate speakers. The result is uncompromising flexibility and unmatched power delivery. Adjustable Gain for Versatility With selectable gain levels of +30dB or +24dB, the MA-1 adapts to different preamplifiers and speaker systems. This ensures optimal matching and consistent performance in varied setups. Surging Power & Energy Control The MA-1 features independent transformers for each channel, ensuring a true dual-mono design. A combined 1250VA toroidal power supply delivers raw energy with precision. Each channel houses 14 capacitors (6,800µF each), forming a capacitor matrix with a total capacity of 190,000µF. This parallel capacitor design lowers internal resistance, enabling rapid current delivery and effortless handling of demanding passages, from thunderous bass to intricate dynamics. H-Shaped Chassis & Refined Craftsmanship The unique H-shaped structure—a hallmark of the M Series—was perfected over two years of research. A 20mm CNC-machined aluminium plate acts as the backbone, supporting all components and creating multiple isolated chambers. This reduces interference, enhances rigidity, and provides symmetry for both left and right channels. Every surface undergoes multiple CNC machining and fine treatments, resulting in a matte texture that radiates refinement and luxury. Silent Cooling – Intelligent and Unobtrusive Thermal stability is crucial for consistent performance. The MA-1 integrates dual temperature sensors on the main heatsink, constantly monitored by an MCU. When needed, a 7.4-inch ultra-quiet fan activates automatically, dynamically adjusting its speed for optimal cooling. Thanks to the isolated airflow duct design, no electronic components are exposed to dust, ensuring reliability and silence—even during long listening sessions. Elegant & Refined Industrial Design The MA-1 continues Matrix Audio’s tradition of combining aesthetic beauty with functional precision. Clean lines, matte finishes, and precision machining reflect not only advanced engineering but also a distinctive, timeless style. From Ears to Heart The Matrix Audio MA-1 power amplifier goes beyond performance—it creates an emotional connection. With rich, textured bass, crystal-clear highs, and exquisite detail, it immerses listeners in the soul of the music. Every note resonates with passion and precision, making each listening experience deeply moving. Like every product in the M Series, the MA-1 is the result of relentless innovation, meticulous refinement, and an unwavering pursuit of perfection.
