The Stellar P3 PowerPlant takes your incoming AC power and converts it to DC, similar to what comes out of a battery, and then, with patented PS Audio technology, regenerates and produces new sine-wave-perfect, regulated, high-current AC power. In the process of regeneration, any problems commonly found on your power line, such as low voltage, distorted waveforms, sagging power, flat-topping, and noise are eliminated. The input voltage to the PowerPlant is fully protected by state-of-the-art clamping devices and the output is fully regulated so even large voltage swings that would normally damage connected equipment are made safe by either clamping or regulating. With your system powered directly from the ouput of the Stellar P3, dynamics and openness are breathtaking. New voices, new harmonics, and a renewed sense of musicality are yours the moment the P3 starts up.This is one of the most important pieces of audio equipment you can own, building a firm and reliable foundation for your system that will serve you for years to come. Not suited for class A or A/B amplification in 220V models.
