Taxes & Shipping Included
The Harmony GaNM Monoblock Amplifiers complete the LAiV series, designed for high-level audio performance. Featuring a fully balanced design and next-generation GaN-FET tech, each channel provides 200W of pure, high-current power, ensuring precise control and exceptional musical fidelity. Dive deeper into the details.
At LAiV, we believe that performance and design should go hand in hand. The Unified Harmony Series Design ensures that every component in the Harmony lineup—be it a DAC, headphone amplifier, DDC, or power amplifier—shares a consistent visual identity. From the sleek brushed finish to the precisely machined corners and matching dimensions, each unit is crafted to stack perfectly, creating a seamless and elegant audio system that looks as refined as it sounds.
Unified design philosophy
Beyond aesthetics, the unified design philosophy also focuses on practical integration. Thoughtful considerations like aligned display windows, uniform control interfaces, and matching power and I/O placements make setup intuitive and user-friendly. This approach reduces visual clutter and enhances the feeling of cohesion, allowing users to focus on their music—not on managing cables or mismatched gear.
Unibody CNC Aerospace-Grade Aluminum
Crafted from a single block of aerospace-grade aluminum using precision CNC machining, the Harmony GaNM delivers exceptional durability, a refined finish, and effective heat dissipation, all while exuding premium quality.
GaN Systems Technology
At the heart of the Harmony GaNM lies GaN Systems Technology, leveraging advanced Gallium Nitride (GaN) transistors to deliver exceptional speed, efficiency, and sonic purity. Unlike traditional silicon-based designs, GaN transistors switch faster, with lower losses and significantly reduced distortion. This allows the amplifier to respond to musical signals with far greater agility and control, resulting in a sound that is effortlessly dynamic, transparent, and free from the constraints of conventional power stages.
By embracing GaN technology, the Harmony GaNM achieves cleaner transients, deeper bass, and more refined detail, especially at low-level passages where precision matters most. The improved power efficiency also translates into lower thermal stress and compact form factors without compromising output power or performance. It’s a future-forward design choice that elevates both the technical and emotional experience of music playback.
Ultra-low Noise Power Supply
The ultra-low noise power supply is meticulously engineered using the advanced NXP TEA2017AAT controller. This smart chip integrates both PFC (Power Factor Correction) and LLC resonant topology into a compact SO16 package, significantly reducing the number of external components required while enabling cleaner, more efficient energy conversion. The result is a stable and refined power delivery system that forms the foundation of the GaNM’s exceptional sonic performance.
Infineon Silicon Carbide CoolSiC™ MOSFETs
To ensure maximum efficiency and reliability, the power supply features premium components such as Infineon Silicon Carbide CoolSiC™ MOSFETs, known for their high switching efficiency, low on-resistance, and extended lifespan. Complementing these are Rubycon electrolytic capacitors from Japan, chosen for their excellent temperature stability and longevity—often exceeding ten years in ideal conditions. Together, these components deliver a consistently stable voltage and current output, crucial for maintaining ultra-low noise and minimizing signal interference.
Robust Protection Circuitry
From over-voltage and over-current protection to input undervoltage and surge shielding—ensuring safe operation under any condition. It supports wide voltage input (90–264Vac) for global compatibility and meets stringent EMI standards suitable for medical-grade applications. With its fanless, high-density design and ripple-suppression capabilities, this power supply guarantees both quiet operation and superior electromagnetic compatibility, letting the music shine without distractions.
True Balanced High Power Output
The Harmony GaNM is designed with a true balanced architecture, meaning both the input and output stages operate symmetrically with completely isolated signal paths for the positive and negative phases. This ensures that common-mode noise is effectively canceled out, resulting in an ultra-clean signal with improved dynamic range and lower distortion. By eliminating the grounding issues common in single-ended designs, true balanced output delivers a more stable, noise-resistant connection—especially beneficial in high-resolution, reference-grade audio systems.
Capable of delivering 200 watts per channel into 8 ohms, the Harmony GaNM provides ample headroom to effortlessly drive even demanding speakers with precision and authority. This high power output is maintained without sacrificing detail or finesse, offering an engaging and transparent sonic experience. Whether you're listening at low levels or pushing the volume, the amplifier maintains complete composure, preserving musical nuance and control across the entire frequency spectrum.
Design That Prioritizes User Comfort and Functionality
The Harmony GaNM is thoughtfully designed to prioritize user comfort and everyday functionality without compromising its audiophile-grade performance. At the front, a crisp OLED display provides real-time status updates with clarity, while subtle yet effective left right channel LED indicators allow for quick identification of left and right monoblocks in multi-unit setups. Around the back, the inclusion of both 12V trigger input and output ensures seamless integration with other components in your system—allowing synchronized power control for a more streamlined and elegant listening experience. Every detail, from visual feedback to system control, is crafted to make the user experience intuitive, modern, and refined.
