JADIS Electronics is a French maker of hand-assembled tube amplifiers, founded in 1983 by devoted audiophiles in Villedubert. Staying true to its original philosophy across generations, the brand builds every amplifier around its own in-house, hand-wound output transformers—cast in a special resin for durability, waterproofing, and thermal stability—delivering exceptional load control and wide dynamic range. The result is amplification engineered to partner confidently with virtually any loudspeaker, combining artisanal craftsmanship with technical rigor for music lovers who demand faithful, emotionally engaging reproduction.
