Unified design philosophy.
The unified design philosophy focuses not only on aesthetics but also on practical integration. Thoughtful considerations such as aligned display windows, consistent user interfaces, and appropriate placement of power supplies and I/Os make setup intuitive and user-friendly.
This approach reduces visual clutter and increases the sense of cohesion, allowing users to focus on their music—not managing cables or mismatched devices.
Unibody CNC aerospace-grade aluminum.
Crafted from a single block of aerospace-grade aluminum with precise CNC machining, the Harmony GaNM offers exceptional durability, a refined finish, and effective heat dissipation while exuding premium quality.
GaN system technology.
At the heart of the Harmony GaNM is GaN system technology, which utilizes advanced gallium nitride (GaN) transistors to deliver exceptional speed, efficiency, and sonic purity. Unlike conventional silicon-based designs, GaN transistors switch faster, with lower losses and significantly reduced distortion. This allows the amplifier to respond to musical signals with much greater agility and control, resulting in effortlessly dynamic, transparent sound free from the limitations of conventional power amplifiers.
By using GaN technology, the Harmony GaNM achieves cleaner transients, deeper bass and finer details, especially in quiet passages where precision is most important.
Improved energy efficiency also results in lower thermal load and compact form factors without compromising power output or performance. This is a forward-looking design decision that enhances both the technical and emotional experience of music playback.
Ultra-low noise power supply.
The ultra-low-noise power supply was carefully engineered with the advanced NXP TEA2017AAT controller. This intelligent chip integrates both PFC (Power Factor Correction) and LLC resonant topology in a compact SO16 package, significantly reducing the number of required external components while enabling cleaner, more efficient power conversion.
The result is a stable and sophisticated power supply system that forms the basis for the exceptional sound performance of the GaNM.
To ensure maximum efficiency and reliability, the power supply is equipped with high-quality components such as Infineon Silicon Carbide CoolSiC™ MOSFETs, which are known for their high switching efficiency, low on-resistance and long service life.
Added to this are Rubycon electrolytic capacitors from Japan, selected for their excellent temperature stability and longevity, often exceeding ten years under ideal conditions. Together, these components ensure consistently stable voltage and current output, which is critical for maintaining an extremely low noise level and minimizing signal interference.

Robust protection circuits
From overvoltage and overcurrent protection to input undervoltage and surge shielding, it ensures safe operation under all conditions. It supports a wide input voltage (90-264Vac) for worldwide compatibility and meets strict EMI standards suitable for medical applications.
With its fanless, high-density design and ripple suppression features, this power supply ensures both quiet operation and excellent electromagnetic compatibility, allowing the music to play without distraction.
True symmetrical high output power.
The Harmony GaNM is equipped with a true symmetric architecture, ieBoth the input and output stages operate symmetrically with fully isolated signal paths for the positive and negative phases.
This ensures that common-mode noise is effectively suppressed, resulting in an extremely clean signal with improved dynamic range and lower distortion. By eliminating the grounding issues common to single-ended designs, a true balanced output provides a more stable, low-noise connection, which is particularly beneficial in high-resolution, reference-quality audio systems.
With an output of 200 watts per channel at 8 ohms, the Harmony GaNM offers sufficient headroom to effortlessly drive even demanding speakers with precision and authority.
This high output is maintained without any loss of detail or finesse, providing an engaging and transparent sound experience. Whether listening at low levels or turning up the volume, the amplifier maintains complete composure, retaining musical nuance and control across the entire frequency spectrum.
Design That Prioritizes User Comfort and Functionality.
The Harmony GaNM is designed to prioritize user comfort and everyday functionality without compromising audiophile performance.
On the front, a crisp OLED display provides real-time status updates with clarity, while subtle but effective LED indicators for the left and right channels allow for quick identification of the left and right monoblocks in multi-unit setups.
On the rear panel are both a 12V trigger input and a 12V output, ensuring seamless integration with other components in your system and enabling synchronized power control for an optimized and elegant listening experience.
Every detail, from visual feedback to system controls, has been designed to make the user experience intuitive, modern, and sophisticated.
