AudioQuest Storm Thunder Power Cable - C19

AudioQuest power cables regularly receive awards from the specialized press and enjoy solid recognition among High-Fidelity enthusiasts. The noticeable improvements achieved over stock power cords account for their lasting success.

The AudioQuest Storm Thunder 16A / 230V with C19 connector belongs to the new generation of mains cables from the American manufacturer's Storm series. As the entry model in this line, it integrates the active DBS (Dielectric-Bias System). This C19 version is specifically engineered to power high-current-draw electronics, such as power amplifiers, active subwoofers, and power conditioners.

AudioQuest Storm Thunder 16A / 230V C19: Features

This power cable utilizes Perfect-Surface Copper (PSC) conductors combined with a Long-Grain Copper (LGC) core. This combination effectively reduces Transient Intermodulation Distortion (TIM) and enhances playback precision.

While low resistance is essential to handle high current demands, a cable's characteristic impedance remains a critical factor in ensuring optimal performance.

Unlike many cables that compress transients, AudioQuest mains cables combine low DC resistance with ZERO characteristic impedance. This design delivers uncompressed high-current transients, an essential asset for components fitted with a C19 connector.

AudioQuest Storm Thunder 16A / 230V C19: Shielding & DBS

The Storm Thunder features AudioQuest's proprietary DBS (Dielectric-Bias System). An external battery pack applies a constant 72V electrostatic bias across the cable's shield. The dielectric materials used in shielding directly impact signal integrity.

The DBS biased shielding (patented by AudioQuest) creates a stable and powerful electrostatic field that polarizes the insulation, effectively reducing noise and preventing RF interference from entering sensitive electronics.

The DBS batteries offer an estimated lifespan of approximately 10 years. An integrated test button allows for easy battery status checks.

AudioQuest Storm Thunder 16A / 230V C19: Current Capacity

The Storm Thunder cable delivers a 16A current capacity, making it exceptionally well suited for energy-hungry equipment.

Power amplifiers present a real challenge for any power supply, as their transient current demands—though brief—can exceed average (RMS) current draw by several times.

Unlike many high-end power cords whose characteristic impedance restricts transient current, the Storm Thunder is engineered to meet these dynamic demands without compression, regardless of volume levels or musical complexity.

AudioQuest Storm Thunder 16A / 230V C19: Listening Test

Upon listening, the AudioQuest Storm Thunder effectively reduces mains noise and subjective distortion in high-end audio/video systems.

Playback gains transparency, fidelity, and dynamic scale across the spectrum. The bass range is literally transformed: deeper, better articulated, and endowed with impressive dynamic impact.

The listening experience becomes more open and fluid, showing a clear improvement in spatial imaging and instrument placement precision.

Thanks to its 16A rating, the AudioQuest Storm Thunder 16A / 230V C19 power cable easily handles transient current peaks well beyond its continuous RMS rating. It is perfectly matched for power blocks, high-power integrated amplifiers, active subwoofers, power strips, and power conditioners.
