About the Duke
The Running Springs Audio Duke is a compact yet heavy power conditioner weighing 24 lbs (11 kg), roughly the size of a loaf of bread. It features a non-ferrous high-quality aluminum chassis to avoid magnetic interference, internal Cardas wiring, and proprietary high-frequency CNDI & DMS passive filters that lower noise floor without compromising dynamics or detail. It uses custom-designed platinum foil capacitors with precision-matched tolerances and synthetic matrix hand-wound inductors for superior resonance control. The unit includes carbon fiber feet and internal carbon fiber resonance vibration control for improved isolation and sound quality. It has a high-current, sonically invisible circuit breaker for protection without diminishing current flow. The Duke supports up to 2400 watts power needs and comes with a 20A power inlet and two American style outlets. It is bundled with a 20A Cardas Golden Reference Mongoose power cord developed in conjunction with Cardas. The Duke is praised for significantly lowering system noise floor, improving sound clarity, coherence, and dynamic contrast, making listening effortless and untiring. It is considered good value given the included premium power cord and advanced internal components. The unit is designed without a power switch to avoid adverse effects on sound quality and includes carbon fiber spikes for further vibration isolation.
