Devialet

Devialet is a French audio company from Paris, founded in 2007 by Quentin Sannié, Pierre-Emmanuel Calmel, Emmanuel Nardin and Mathias Moronvalle. It became known for amplifiers built on its own Analog Digital Hybrid (ADH) technology and later for the Phantom wireless speakers.

Range

• The Expert Pro amplifiers (Expert 140 Pro, 220 Pro and 250 Pro, plus the Dual models 210, 440 and 1000) combine amplifier, DAC and streamer. They support Roon Ready, UPnP, AirPlay and Spotify Connect and have a phono stage.
• Phantom wireless speakers, the Dione soundbar, the portable Mania speaker and the Gemini earbuds.
• Devialet had around 160 patents in 2018, among them for technologies such as Heart Bass Implosion and Speaker Active Matching.

Ownership

Devialet raised €100 million in 2016 from investors including Foxconn. After a period of falling sales it was restructured in 2024: a round led by Korelya Capital, with Bernard Arnault and Xavier Niel, brought in €30 million, followed by around €10 million more. Jacques Demont has been CEO since January 2024.
