PS Audio - Stellar Power Plant 3 - Power Regenerator
Providing 300 watts of continuous power output and peaks of 900 watts, the P3 is the perfect companion for source gear and systems running high efficiency Class D amps like the Stellar M700 monoblocks. Designed with elegant simplicity in mind, the P3 is a plug and play device that will provide you with perfect power without any fuss.
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. Furthermore, power conditioners raise the impedance of the power going to your system, which can bleach your sound and drain away dynamics. The P3 handles things completely differently. Through the P3’s active regeneration process, it is able to provide perfect power while also lowering the impedance, increasing the dynamics and openness of your system.
Best of all, the P3 features overbuilt surge and spike protection, meaning you can rest easy knowing your system is safe.
Don’t starve your music or risk damaging your equipment. A P3 gives you greatly improved performance and safety from just plugging into the wall socket and far better dynamics, more authoritative bass and a much bigger, more open soundstage.

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.
How It Works
The Stellar Power Plant 3 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.
Since the introduction of Power Plant regenerator technology in 1997 many reviewers, as well as many thousands of customers around the world, have experienced for themselves just how critical, essential and unique a Power Plant is. One long-time reviewer remarked that “It is the first component anyone serious about high-quality audio should get.”
It’s good to understand the importance of power in a high-end audio system. Everything we hear through our system is really the power from our home’s wall socket manipulated by our electronics to make music through our speakers. The quality of that power is critical to the success of any high-end system.
- Legacy power conditioners
Traditional power conditioners have been widely available for several decades and range in price from a few dollars to multiple thousands.
Most power conditioners on the market today are passive filters. This means there are only passive parts inside such as capacitors, resistors, transformers and coils of wire. Power conditioners do not have the ability to add missing energy back onto the power line to correct for the serious issues in the AC, nor can they lower output impedance—critical to high-performance audio.
While some respected high-end power conditioners do provide better sound for many systems, they are only scratching the proverbial surface—unable to address the fundamental problems found on the AC line. They cannot rise to the level of an active regenerator ensuring your listening experience will always be the same. Quite simply put, by relying on passive conditioners to clean AC power, one relinquishes the performance, security, and reliability of an active PS Power Plant.
- Power Plants are not power conditioners
Power Plants are personal AC generators that provide hard-working perfected results from the AC power line. Power regeneration uses active components like those found in large and powerful audio amplifiers to rebuild the AC power and produce clean, clear, distortion-free, regulated AC to the equipment.
Power Plants also provide excellent protection and cleaning of radio, cell phone, and computer interference, but more importantly, regeneration provides a steady, regulated, ultra-low impedance source of pure AC, unaffected by the equipment’s demands for power.
The key to the Power Plant’s success and what makes it so unique in the industry is the way it makes the power better.
Instead of simple filtering, as a legacy power conditioner does, the Power Plant repairs the main power issues caused by the equipment itself: dynamic fluctuations.
Dynamic fluctuations occur with every power amplifier or receiver on the market. When a loud musical passage is reproduced, the power amplifier draws more power from the wall to feed the loudspeakers. When this occurs, the voltage at the wall decreases in direct relationship with the loudness of the musical passage. Louder is worse.
- Traditional power conditioners only worsen this already bad situation
If, on the other hand, the system is powered from a Power Plant AC regenerator, the problem is entirely eliminated. Dynamic voltage fluctuations are stopped completely and the power amp receiving perfectly regulated, steady AC power regardless of the demands from the power amplifier.
In a high-end system where perfection is hoped for and compromise is not an option that’s acceptable, the improvements brought by a Power Plant are instantly recognized with a simple audition that shows both with and without perfected power.
The remote control
Touch the buttons on the Stellar 3 remote control and you can turn the power on and off, activate MultiWave or CleanWave.
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 connected 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 Power Plant 3 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 from the Power Plant 3 remote control can remove this problem from connected transformers resulting in far cleaner audio.
50 times lower output impedance
Low output impedance is critical to maintaining a dynamic and robust presentation. Dynamic sags in the power line occur whenever your power-hungry equipment demands power to drive your loudspeakers or projector, causing noticeable degradation in the performance. Placing anything in the path of the power, like a passive power conditioner, only worsens the problem.
The Stellar 3, on the other hand, regulates the power and provides a constant output regardless of the dynamic demands of power-hungry equipment or your neighbours. When your power amp is asked to produce loud orchestral levels, you want to make sure it has all the power it needs. The Stellar Power Plant 3 has such low output impedance (0.008Ω vs. typical 0.4Ω) that even the hungriest of small to medium sized amplifiers won’t be starved for clean AC power. The results of feeding your equipment with low output impedance are dramatic: unrestrained dynamics even under the loudest passages, an open, wide soundstage that does not collapse with volume and a naturalness to the music that is remarkable.
Owners who have invested in a Stellar Power Plant 3 can rest assured that their connected equipment will be safe from any power line event such as over voltage, under voltage, surges, spikes and potentially threatening problems.
The input voltage to the Power Plant is fully protected by state-of-the-art clamping devices and the output of the Power Plant is fully regulated so even large voltage swings that would normally damage connected equipment are made safe by either clamping or regulating. In most cases, connected equipment enjoys the protection and performance benefits of fully regulated power, even under extreme circumstances.
