Perfection

The engineers at Devialet have sought perfection in every aspect of sound reproduction with the Expert Pro series. But always with the same ambition: to deliver the best performance ever measured at all volumes. Incomparable. Pure sound. Explosive dynamics. Absolute silence. No matter what your source or speakers are. A rare emotional experience.

Radically superior

According to Devialet, the Devialet Expert Pro series integrated amplifier surpasses all existing competing systems and sets a true industry standard. Before the Expert Pro came to life, 10 years of research and development were needed, resulting in over 100 patents. More than 60 international awards later, the Devialet Expert Pro remains the world's most coveted system. Radically superior.

Architecture

Devialet's integrated and virtually infinitely upgradeable architecture adapts to your desires. It effortlessly connects to your audio source and speakers with absolute precision. Built from a single block of pure aluminum, the Expert Pro combines extreme finesse with optimal temperature management.

Technologies

The Devialet Expert Pro series amplifiers utilize Devialet's own groundbreaking technologies, such as ADH Analog Digital Hybrid Amplification, a system that combines the best of both worlds of Class A and Class D amplification. Additionally, the Expert Pro uses SAM Real-Time Speaker Matching, DAC Magic Wire, and RAM Dynamic Phono Staging. The ultimate expression of Devialet's most groundbreaking innovations. Light years ahead.

Flexibility

With the Devialet Expert Pro, there are no limits. With the online Expert Pro Advanced Configurator, you can seamlessly adjust your system settings with unprecedented precision. From input and output definitions to the exact specifications of your turntable's cartridge, the Devialet Expert Pro allows you to build your own audiophile system.

SAM

SAM stands for Speaker Amplifier Matching and is a technology developed by Devialet's engineers. SAM uses custom profiles to provide the exact perfect amplification to your speakers. This allows your speakers to perform like never before.
