High-End GaN Stereo Amplifier with Aerospace Engineering and True Balanced Architecture
The Laiv Harmony GaNM is a state-of-the-art stereo power amplifier engineered for audiophiles who demand absolute transparency, dynamic accuracy, and superior build quality. Built on advanced Gallium Nitride (GaN) FETs, featuring a true balanced circuit, and crafted from aerospace-grade aluminum, the GaNM brings together cutting-edge power technology and elegant industrial design to elevate any high-fidelity system.
GaN Systems Technology - Speed, Efficiency, and Sonic Accuracy
At the core of the Harmony GaNM lies GaN Systems Technology, utilizing high-speed GaN (Gallium Nitride) transistors that outperform traditional silicon-based designs in virtually every way
.
GaN FETs allow for:
- Faster switching speeds for precise transient control
- Lower switching losses and dramatically reduced distortion
- Increased power efficiency and lower thermal stress
This results in a sound signature that is dynamic, refined, and incredibly revealing. Transients are tighter, bass is deeper and more articulated, and microdetails are retrieved with pinpoint accuracy—even at low-level passages. GaN technology also contributes to the amplifier’s compact, fanless form factor without compromising output power or thermal performance.
Fully Balanced Circuit Topology - Clean, Powerful, and Stable Output
The Harmony GaNM features a fully balanced circuit architecture, with symmetrical signal paths for both input and output stages.
This ensures:
- Exceptional rejection of common-mode noise
- Lower total harmonic distortion
- Improved signal integrity across the frequency range
Elimination of ground loop issues common in unbalanced designsDelivering 200 watts per channel into 8 ohms, the amplifier is capable of driving a wide range of speakers with complete authority and finesse. Whether at moderate volume or high-output levels, the GaNM maintains composure, resolution, and control.
Ultra-Low Noise Power Supply - Clean Power, Maximum Fidelity
The Harmony GaNM is equipped with a custom-engineered switched-mode power supply designed for audio applications. At the heart of the design is the NXP TEA2017AAT controller, integrating power factor correction (PFC) and an LLC resonant converter topology in a compact, efficient layout. The result is precise voltage regulation and ultra-low ripple, preserving signal integrity across the amplifier’s operating range.
Key components include:
- Infineon Silicon Carbide CoolSiC™ MOSFETs - for high-speed switching and minimal conduction loss
- Rubycon electrolytic capacitors (Japan) - known for long life, low ESR, and temperature stability
- Medical-grade EMI compliance - for quiet operation in sensitive environments
The fanless design and high efficiency allow the amplifier to operate silently while minimizing electromagnetic interference (EMI), ensuring that nothing stands between your system and the music.
Aerospace-Grade Chassis - Built for Performance and Durability
Precision-machined from a single block of aerospace-grade aluminum, the Harmony GaNM enclosure offers:
- Exceptional mechanical rigidity
- Effective passive heat dissipation
- A clean, elegant aesthetic with refined surface finishing
This monolithic chassis ensures vibration resistance, structural longevity, and thermal efficiency—all critical factors in achieving consistent performance in high-end audio systems.
Unified Harmony Series Design - A System-Wide Visual and Functional Identity
The Harmony GaNM follows Laiv’s Unified Harmony Series Design philosophy, allowing seamless integration with other components in the Harmony Series such as DACs, DDCs, and headphone amplifiers.
Key design features include:
- Matching chassis dimensions and brushed finish
- Aligned OLED display placement and control interface layout
- Consistent rear I/O positioning for cleaner cable management
This approach not only creates a visually harmonious system but also simplifies setup and daily use by standardizing control logic and ergonomics across the product line.
User-Focused Functional Design
Designed with real-world usability in mind, the Harmony GaNM includes features that enhance everyday operation without compromising its high-end performance:
- Front-mounted OLED display for clear status monitoring
- Left and right channel LED indicators for easy monoblock identification in dual-mono configurations
- 12V trigger input and output for synchronized system power control
- Wide voltage input support (90-264Vac) for global compatibility
All elements are designed to ensure smooth integration into complex systems while maintaining modern, minimalist aesthetics.
