Pierre-Emmanuel Calmel invented a revolutionary technology that transformed sound amplification:
The ADH Intelligence. The first hybrid technology that associates the preciseness of Analog amplification (Class A) to the power of Digital amplification (Class D) allowing Devialet products to reach a never heard before sound quality.
Founded and based in Paris, Devialet is now the international leader for high end amplifiers. Only 4 years after the first launch, Devialet has become a market leader thanks to the continuous, drastic and revolutionary inventions in audio engineering
