Description

Stellar PowerPlant 3

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

The Stellar Power Plant 3 stands on the shoulders of giants. Built as an evolution from our renowned P12, P15, and P20 the P3 is our most affordable regenerator – perfect for powering sources and small to medium systems. Power Plants generate sine-wave-perfect, regulated, high current AC power from your home’s AC. Problems on your power line such as low voltage, distorted waveforms, sagging power, and noise are eliminated and the power quality enhanced. 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.

DESIGN

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 and worry free protection from surges, spikes, and ugly power without any fuss. Regulate, remove distortion, and get better performance.

APPLICATION

The P3 is the perfect companion for improving system performance and ensuring a safe environment for you Hi-Fi system. Providing 300 watts of continuous power output and peaks of 1000 watts, the P3 is just right for source gear or an entire systems running small to medium class AB amps or larger 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.

OVERVIEW

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.

OUTPUT

The P3 takes in your home’s noisy, distorted, and unregulated AC and outputs pure and perfect power that dramatically enhances sound quality. It does this by rebuilding the AC, lowering output impedance, and regulating the voltage. Low output impedance is critical to maintaining a dynamic presentation. Powering equipment through a passive power conditioner only worsens the problem and should be avoided. The Power Plant, on the other hand, has such low output impedance (0.008Ω vs. typical 0.4Ω) that even the hungriest of amplifiers won’t be starved for clean AC power. When your amp is asked to produce loud orchestral levels, you want to make sure it has all the power it needs and only a Power Plant provides a constant output regardless of the dynamic demands of equipment or your neighbors. Power Plants also generate new waveforms that enhance the capabilities of your equipment. MultiWave extends the peak charging time of the sine wave so connected equipment has more energy storage and less power supply ripple. The results are dramatic: a bigger more musically accurate soundstage than with a simple sine wave.

PROTECTION

An electrical surge, or spiked transient, is an intense, short-duration voltage increase that travels through electrical wiring in our homes. It can severely damage connected equipment. Shielding devices from these potential electrical problems is mandatory if we’re to protect our investment and ensure the safety of our homes. These electrical transients are not the only potentially damaging problems faced by our sensitive audio systems. There are also sustained over-voltage conditions that many surge suppression devices will not be able to protect equipment from. Owners who have invested in a Power Plant can rest assured 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.

Why Choose PS Audio

PS Audio is one of America’s most respected high-end audio manufacturers, building a loyal worldwide following through a combination of innovative engineering, strong customer support, and products designed around real musical enjoyment rather than technical spectacle alone. Founded by Paul McGowan in Colorado in 1974, the company has spent decades developing amplifiers, DACs, streamers, and power regeneration products that focus heavily on preserving musical realism, lowering system noise, and improving long-term listening satisfaction.

At HeyNow Hi-Fi, PS Audio has become one of the most consistently successful and widely loved brands amongst clients because the products combine genuine high-end performance with an inviting and highly engaging sound character. There is a naturalness and ease to the presentation that encourages longer listening sessions, while still delivering the scale, dynamics, and resolution expected from serious high-end systems.

Another aspect that makes PS Audio particularly appealing is the company’s consistency in industrial design and long-term product philosophy. Rather than constantly redesigning aesthetics, button layouts, and visual styling with every new release, PS Audio products maintain a cohesive and timeless appearance across generations. This allows customers to progressively build and expand their systems over time without older components feeling visually obsolete each time a new model is introduced.

Signature Design and Sound

PS Audio products are designed and engineered in the USA with a strong focus on low-noise design, analogue-like musicality, and practical long-term usability. Over the years, the company has developed a number of highly regarded proprietary technologies across digital playback, amplification, and power management.

One of the most significant areas of PS Audio’s engineering philosophy is power regeneration. Rather than simply filtering incoming AC power, PS Audio regenerators actively rebuild a new low-distortion AC waveform designed to provide connected equipment with cleaner, more stable power. In highly resolving systems, this can contribute to lower noise floors, improved dynamics, greater image stability, and a more natural and relaxed presentation.

PS Audio’s digital products have also earned strong recognition for their smooth, spacious, and highly musical sound. Rather than sounding overly sharp or clinical, the presentation feels dimensional and organic, with impressive tonal density and excellent long-term listenability. Music flows with a sense of ease and realism that appeals strongly to listeners who value emotional engagement as much as technical performance.

The company’s amplification platforms have evolved significantly over the years, particularly through the success of the BHK Signature series and the newer PMG range. These designs combine exceptional control and dynamic capability with a natural tonal presentation that avoids sounding sterile or overly aggressive, even within highly resolving systems.

PS Audio Product Range

The PS Audio range available through HeyNow Hi-Fi includes DAC streamers, integrated amplifiers, mono power amplifiers, power regenerators, network audio products, and digital playback solutions designed to operate cohesively within high-performance music systems.

Products including the DirectStream DAC platforms, Stellar series, BHK Signature amplifiers, PMG range, and Power Plant regenerators have developed particularly strong followings amongst listeners seeking systems that combine refinement, musicality, and long-term ownership satisfaction. The company’s products are also supported through ongoing firmware development and strong after-sales support, helping protect long-term product value and usability.

At HeyNow Hi-Fi, Geoff and his experienced system setup team provide assistance with system matching, streamer integration, power optimisation, and complete system configuration to ensure PS Audio products perform at their full potential within each customer’s listening environment.
