Jadis Electronics, founded in 1983 near Carcassonne in Villedubert, France, by self-taught valve amplifier designer André Calmettes alongside partner Jean-Paul Caffi, embodies a passion for recapturing the emotion of live music through tube technology. Born from Calmettes' amateur radio tinkering and inability to afford commercial amps, the brand quickly earned acclaim for its handmade craftsmanship, with every component meticulously selected and assembled. The name "Jadis," meaning "in olden days," evokes nostalgia while signaling a commitment to timeless excellence in French hi-fi heritage.
The company specializes in high-end valve amplification, producing pure class-A stereo and power amplifiers, preamplifiers, and RIAA phono stages, all handcrafted with proprietary output transformers. These transformers, wound by hand and encased in special resin for thermal stability and low noise, handle up to 2500 watts before saturation, ensuring absolute stability across any load. Jadis has expanded modestly into turntables, CD players, and DACs, maintaining a focus on analog warmth over digital proliferation, with no foray into speakers, headphones, or cables.
Positioned firmly in the high-end audiophile market, Jadis commands reverence as the "Rolls-Royce" of tube amps, prized by discerning collectors for its dynamic, uncolored sound and indestructible build—transformers even carry lifetime guarantees. Recent ownership changes, including Jérémie Malfroot's acquisition, preserve this boutique ethos amid global expansion, appealing to buyers seeking artisanal French mastery over mass production.
