Key Features

The H400 is a Class AB amplifier, delivering 250W of power into 8 ohms, and is stable down to 2-ohm loads. With a remarkable damping factor of 4000, H400 ensures tight control over your speakers, providing precise and dynamic sound. H400’s dual mono construction and symmetrical layout ensure superior sound quality. The absence of an equalizer preserves signal integrity, while our SoundEngine 2 technology offers instant  distortion correction during amplification. This results in a detailed, agile sound, deliver ing both punch and finesse while maximizing power efficiency. Experience your favorite  music with a new level of clarity and richness, as the H400 faithfully reproduces every  nuance and detail. 

The H400 incorporates many of the same advanced features found in our reference inte grated amplifier, ensuring high performance and value. It includes the same Dual Mono  design, the same robust streaming platform, and a high-quality bit-perfect DAC based  on the one in the H600. These shared features mean that the H400 delivers similar high  standards of sound quality and versatility, making it a remarkable choice for discerning  listeners.  

Every aspect of the H400 has been meticulously developed in-house, ensuring unparal leled quality control and cohesive design. This streamlined approach eliminates unneces sary steps and complications, allowing our engineers to focus on innovation and perfor mance. By keeping development under one roof, we guarantee that every component and feature is perfectly integrated, enhancing overall efficiency and reliability. This in-house  development strategy also allows for faster implementation of new features and improve ments, ensuring the H400 remains at the forefront of audio technology.

Streaming and Control App 

The H400 is optimized for simplicity, supporting popular streaming platforms such as  AirPlay, Spotify Connect, Roon Ready, Tidal Connect, Google Cast™, and UPnP. Users can  control the amplifier through these services directly. Additionally, our Hegel Control App  provides volume and input control, and access to internet radio, podcasts, and media  server playback, enhancing the overall user experience. Whether you are streaming your  favourite playlist or exploring new podcasts, the H400 makes it easy and enjoyable.
