Description
The Jadis SE300B is a reference single-ended monoblock tube power amplifier engineered around two 300B triode tubes operating in parallel pure Class A to deliver 10W RMS per channel. Built with zero global negative feedback, it features a double-triode 6SN7 driver stage operating at 400V in cascade configuration and an output stage powered at an optimized 320V. To preserve delicate harmonic detail and eliminate line disturbances, both the driver and power stages benefit from independent vacuum-tube regulated power supplies. Delivering a frequency response of 20Hz to 20kHz (-3dB) with automatic biasing, point-to-point hand wiring, and Jadis' signature polished stainless-steel chassis with gold-plated faceplates, the SE300B provides unmatched liquidity, holographic imaging, and breathtaking tonal purity.

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.
