Devialet was born in 2007 as a response to the paradox that whilst 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 detail that make music what it is, continues to elude us.

The company 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.
