Atoll Electronique IN400SE silver

This product is no longer available for sale!

Overview

The concept of the IN400SE is based on technical and aesthetic choices dedicated to optimal musicality. Mechanically, the chassis is made of 2mm steel, the front panel of 10mm aluminum. The side heatsinks are machined from solid aluminum blocks to absorb mechanical vibrations and ensure perfect heat dissipation. The electrical stages are rigorously dual mono with a specific attenuator per channel and two differentiated star grounds. Each component has been selected by listening and the circuit optimized to refine the bias currents and the feedback ratio. The ultimate goal is to offer maximum power with as much energy in all registers. The result is a listening experience that combines sonic substance and fluidity, naturalness and harmonic richness.

User reviews

Stéphane

After 3 months of use with Fyneaudio 502SP speakers, I can only recommend this exceptional amplifier.
I have a rather challenging room to sound (90m² with a 4.5m ceiling height). Therefore, an excellent power reserve was needed to support the bass, which is why I initially chose this amplifier.
Well, not only does it not strain at all, even at high volume, but the sound is also very dynamic and very refined… The voices are magnificent.
Excellent, truly.

Après 3 mois d'utilisation avec des enceintes Fyneaudio 502SP, je ne peux que conseiller cet ampli exceptionnel.
J'ai pourtant une pièce assez difficile à sonoriser (90m² pour 4, 5m de hauteur sous plafond). Il fallait donc une excellente réserve de puissance pour soutenir les basses, d'où le choix initial de cet ampli.
Et bien non seulement il ne force pas du tout, même à fort volume, mais en plus le son est très dynamique et très fin… Les voix sont magnifiques.
Excellent, vraiment.
