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.
