Product Highlights

Please note: DC Cables are not included from the manufacturer, and this unit does not have them.

The UpTone Audio JS-2 linear power supply features a custom 100VA electrostatically shielded R-core transformer, a choke-filtered topology, and dual independently adjustable outputs delivering up to 7.4 Amps continuous or 10 Amps instantaneous current. This robust component anchors high-end digital front-ends, feeding ultra-clean DC power to sensitive gear like DACs, network routers, and music servers. By generating a benign, low-ripple sine wave rather than harsh high-frequency noise spikes, the unique inductor-capacitor circuit configuration eliminates ultrasonic artifacts. Users can easily select 5V, 7V, 9V, or 12V operation for each output independently via rear-panel switches.

Critical acclaim from media like Audio Bacon highlights its ability to slash the noise floor, injecting dynamic energy and treble realism into connected electronics. Audiophiles and reviewers widely praise this unit for delivering a deeper soundstage and tightening bass articulation when replacing stock switching power supplies. In-depth user evaluations note its exceptional synergy when paired with premium digital-to-analog converters.

Integrating a choke-regulated power supply of this caliber purges the grain and glare that mask low-level musical details. It allows source components to perform at their true design potential, rendering fine acoustic textures with lifelike precision. Upgrading to this unit delivers a massive leap in absolute sonic purity, effortlessly drawing you closer to the performance.
