The best Stereo that Devialet makes, the first step towards a Dual-Mono.

The Expert Pro 220 is designed to meet the demanding needs of audiophiles with full connectivity and the world’s most advanced phono stage.

It includes all Devialet exclusive technologies as well as major innovations developed for the new Expert Pro range.

Able to be linked to a second device to create an Expert 440 Pro, the Expert 220 Pro is the best solution to develop towards the extreme performance of the Dual-Mono configuration.

Your Expert Pro unlike any other Vinyl turntable, CD player, tuner, computer, smartphone, tablet, NAS, online music services, television : the Expert Pro system elevates all of your music.

The Configurator enables you to adjust, with absolute precision, each setting of your audiophile set up.

From defining active sources to setting the specifications of your phono cartridge, create a system unlike any other in the world.

Ready for Devialet OS

Thanks to their unique architecture, Expert Pro systems are capable of integrating hardware and software innovations that will be introduced by Devialet engineers in the future.

Among other major improvements, Expert Pro will be able to integrate the new Devialet OS in 2017.

A free upgrade will soon open the path for many uses of music such as UPnP/DLNA.

In the world of sound, there is a striking paradox:

While Music has never been so accessible in terms of volume, the quality of the sound itself, and the way technologies manage to restitute it, remains questionable.

The purity and thousands of details that make music what it is, continue to elude us.

Devialet was born in 2007, as a response to that very issue.

Their goal: making it possible for a larger number of people to listen to perfectly restituted sound using everyday sound devices. Simple enough, come to think of it!

All their teams are hard at work, turning an insane ambition into an extremely concrete reality.

Step by step, we have sparked a real technological revolution in the audio world that got in motion thanks to some radical innovations.

Since their creation, they have registered 200+ patents.

Devialet’s DNA finds its source in the influence of philosophers from the Enlightenment era.

theirr name is a reference to engineer Guillaume Vialet, a companion of Diderot and contributor to the French Encyclopedia. Vialet is widely known as one the intellectuals who, through their intellectual, cultural and scientific commitment, contributed to the betterment of the world.
