Stellar Power Plant 3

Our most affordable AC regenerator, the P3 protects, purifies, and powers sources, as well as small to medium sized systems.

The Stellar P3 PowerPlant provides greatly improved performance and safety from just plugging into the wall socket, along with far better dynamics, more authoritative bass, and a much bigger, more open soundstage than any passive power conditioner on the market. Featuring overbuilt surge and spike protection, you can rest easy knowing your system is safe.

The Stellar P3 PowerPlant features an ultra-low impedance analog AC power amplifier, pure DSD FPGA based analog sine wave regenerator, and low distortion high-dynamic-peak-capable outputs found only in PS Audio PowerPlants. Designed with elegant simplicity in mind, the P3 is a plug and play device that will provide you with perfect power without any fuss.


Providing 300 watts of continuous power output and peaks of 1000 watts, the P3 is the perfect companion for source gear and systems running high-efficiency Class D amps like the Stellar M700 monoblocks. The P3 will bring forth all that's possible from your HiFi system, ensuring you get the same great performance every time you listen.


Power Plants are regarded for their ability to reduce noise and THD to virtually zero while providing rock steady voltage output. Traditional power conditioners can only affect a portion of incoming noise and are unable to compensate for over or under voltage. 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.
One of the major advantages of generating new power from old is the ability to also generate new waveforms that enhance the capabilities of the power feeding your equipment. MultiWave extends the peak charging time of the sine wave so connected equipment has more energy storage and less power supply ripple. Turning MultiWave on is like adding a larger capacitor bank to your conected equipment's power supply. The audible results are dramatic and produce a bigger soundstage that sounds far more natural than with a simple sine wave.
CleanWave is another feature of the Stellar P3 PowerPlant and helps connected equipment demagnetize their transformers. AC power is never quite symmetrical and the small asymmetry that occurs can magnetize connected power transformers. Activating CleanWave fromt the P3 remote control can remove this problem from connected transformers resulting in far cleaner audio.
