LAIV HARMONY GANM Power Amplifier Black

LAiV Harmony GaNM: Aesthetic and ergonomic heritage of the Harmony range

The design of the Harmony GaNM fits harmoniously into the aesthetics of LAiV Audio's Harmony range, with a superb CNC-machined aluminum chassis that combines rare elegance with efficient thermal dissipation.

Integration within the Harmony range goes beyond appearance; the user experience is also designed for perfect synergy between devices. The alignment of screens, the uniformity of controls and the matching of connectors facilitate intuitive and ergonomic installation, reducing visual clutter and reinforcing the cohesion of the system, allowing the listener to concentrate fully on the music.

LAiV Harmony GaNM: The power and purity of GaN transistors

At the heart of the Harmony GaNM lies GaN Systems technology, using gallium nitride (GaN) transistors for remarkable speed, efficiency and sonic purity, delivering 200W of amplification per mono block. Unlike traditional silicon transistors, GaN transistors switch faster, with significantly reduced energy loss and distortion. This enables the amplifier to react to signals with superior agility, resulting in a dynamic, transparent sound, free from the limitations of conventional power stages.

The adoption of GaN technology enables sharper transient responses, deeper bass and increased richness of detail, particularly in low-level passages. Improved energy efficiency also reduces thermal stress, enabling a more compact chassis design without sacrificing power or performance.

LAiV Harmony GaNM: Ultra-low-noise power stage for optimum sound clarity

The ultra-low-noise power stage is precision-engineered using the advanced NXP TEA2017AAT controller. This intelligent chip integrates power factor correction (PFC) and LLC resonant topology into a compact package, reducing the number of external components and ensuring cleaner, more efficient power conversion. The result is a stable, precise power supply, the foundation of the Harmony GaNM's outstanding sonic performance.

To ensure maximum efficiency and reliability, the power supply features top-of-the-range components such as Infineon's CoolSiC™ silicon carbide MOSFETs, known for their high switching efficiency, low on-resistance and long life. They are complemented by Rubycon electrolytic capacitors, chosen for their excellent temperature stability and longevity. Together, these components provide a perfectly stable output voltage and current, which is essential for maintaining very low noise levels and minimizing signal interference.

Overvoltage, undervoltage and overcurrent protection ensure safe operation over a voltage range from 90V to 264V AC.
