Description
The Jadis JPS2S is a reference two-chassis tube line preamplifier featuring fully balanced XLR topology, engineered to deliver a massive, holographic soundstage with unmatched clarity and natural ease. Its audio circuit employs three ECC83 tubes for line amplification and an ECC82 tube for impedance matching on the CD input, wired entirely point-to-point with high-purity copper and silver conductors and gold-plated terminals. To shield the audio signal from mains interference, it features a dedicated external power supply that regenerates an isolated high-voltage supply at an 80Hz frequency—effectively bypassing standard 50Hz or 60Hz mains noise—regulated by EF86 and EL84 tubes. Equipped with both XLR balanced and RCA unbalanced inputs and outputs, and finished in Jadis' signature polished stainless steel and gold aesthetics, the JPS2S sets a benchmark for spatial openness, dynamic contrast, and reference-grade build quality.

Jadis Electronics: French Legend of Handcrafted Vacuum Tube Audio
Founded in 1983 by André Calmettes in Villedubert, France, Jadis Electronics stands as a global icon in the realm of high-end tube amplification. Born from a profound passion for faithful musical reproduction, the company was established to recreate the raw emotion and atmosphere of live performances within the home. Jadis specializes in designing and handcrafting reference tube power amplifiers, preamplifiers, DACs, and CD players. The beating heart and hallmark of Jadis amplification reside in their custom in-house output transformers, meticulously hand-wound and potted in special resin to guarantee thermal stability, dead-silent operation, and extreme durability. Operating predominantly in pure Class A, Jadis amplifiers deliver immense dynamic contrast, a velvety low end, and effortless control over demanding speaker loads.
Prior to assembly, every vacuum tube undergoes a multi-stage burn-in and screening process to ensure only the finest matched pairs are implemented. The exquisite chassis, featuring surgical-grade stainless steel and gold-plated front panels, provides instantly recognizable visual elegance. Continual engineering refinements in the latest MkII and MkIII iterations further elevate performance through upgraded internal silver wiring and enhanced power supply filtration. Jadis is built for discerning audiophiles who cherish warmth, natural detail, and expansive spatial imaging backed by French artisan craftsmanship. At Dream Audio, we proudly feature Jadis Electronics as a cornerstone of musical soul and timeless tube engineering.
