The DirectStream P15 Power Plant 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 on your power line such as low voltage, distorted waveforms, sagging power, 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 touch panel

Touch the large, full-colour display on the front of the Power Plant and a whole world of opportunities open up. From here you can measure distortion, both incoming and outgoing, improvement levels, and power consumption. You can also change all your settings such as the turn on/off sequence, adjust the output voltage to the perfect level, turn individual zones on or off and measure the power quality with either the built-in oscilloscope or the THD analyzer.

The P15’s front panel controls offer a wealth of options not normally associated with AC power products such as the ability to measure the distortion of the incoming and outgoing waveforms plus the ability to actually see the waveforms with the colour oscilloscope.

MultiWave

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

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.

200 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 demand power to drive your loudspeakers or projector causing noticeable degradation in the performance. Placing anything in the path of the power, like a power conditioner only worsens the problem.

A Power Plant, 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. Power Plants have such low output impedance that even the hungriest of 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.

100% Protection

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.

High current soft start

Another protective measure found on the P15 is a high power soft start feature that soft starts even the biggest power amplifiers.

With a Power Plant, there’s no longer any need to worry about starting up a power-hungry amplifier. Using the unique high current zone built into the Power Plant, even power amplifiers that might trip a home’s circuit breaker are soft started and power up as nice and polite as could be.

This soft start feature also helps prolong the life of connected equipment from large inrush currents needed to fill up empty power supply capacitors.

Monitor your system’s heartbeat

You can monitor your power quality and performance of your equipment from the front panel of the P15 with both its real-time distortion analyzer and working oscilloscope. Measure everything that’s going on affecting your system’s performance. You can also monitor and control your P15 over the internet from anywhere in the world.

The P15 will monitor your power line quality and report any problems to you through the web page, text or email. It’s up to you. The P15’s real-time and on-line measurement system includes surges, voltage levels, power usage and power quality as measured by THD (Total Harmonic Distortion) on the line.

The data is stored on PS Audio's servers and available via the web interface for the P15. Customers can look at power quality over time, or drill down to specific times of day to find out if there’s a problem involving the home’s power. Sagging voltages, high distortion and multiple brownouts are occurring more than one might think. With the installation of a P15 in the system, you can accurately record events and present them to the utility company for repair or just keep a log.

 

The P15 Power Plant is their second-largest Power Plant, big enough to handle just about any size system. The P15 incorporates their patented, highly efficient, AC regenerator technology. That patent, awarded to PS Audio on October 15, 2007, was the work of our Chief Engineer, Robert Stadtherr who invented a new type of regeneration circuit that improved the efficiency of the classic internal regenerator by a whopping 70% (from 50% to 85%). While others have tried increasing the efficiency of AC regeneration by means of a class D switching amplifier, our patented technology is pure analogue all the way, using a stereo Class A/B power amplifier to output the regenerated AC.

The original design concept for the P10 Power Plant was to build a no-holds-barred AC regenerator without any compromises, such as fans, power and size restrictions, and the P15 is its successor. The unit’s physical requirements, including its massive heat sinks, were created first in PS Audio's mechanical engineering department based on heat dissipation and power supply size requirements.

Now, with over 7 years of field-tested experience under their belts the P10, which enjoys an enviable reliability record for its thousands of worldwide users, paved the way for the next generation Power Plant, the P15.

PS Audio's engineering department started with the proverbial blank sheet of paper and redesigned the internal electronics from the ground up, including an all-new analogue power amplifier and signal source. Because signal purity is so critical to the success of a Power Plant, they turned to the purest and best sounding waveform generator they know of, a DSD DAC. Based on similar FPGA architecture to the DirectStream DAC, the P15’s internal signal source is the cleanest, purest, best-sounding sinewave generator in the history of PS Audio.

Each and every P15 Power Plant is hand-built by skilled artisans that understand each product they build is an investment their customers make in both the product and their company.

Every employee at PS Audio is proud to let the world know it’s “Built-in Boulder.”

 

"The effect on analog and digital sources is equally bold, yet different. Every DAC plugged into the P15 instantly displays less harshness and glare – all the stuff you hate about digital, is now either gone or greatly diminished. Every phonostage exhibited a lower noise floor, especially those with vacuum tubes under the cover, allowing more of the finest musical details to come through. I guarantee you will have at least a few “wow, I never heard that” moments with the P15."

Tone Audio

"The effect of all this effort to deliver clean AC power was not subtle. Every aspect of the sound is touched, elevated, and refined. Everything we seek in great sound, dimension, depth and space, color, dynamics, transparency, and detail are boosted in seeming equal parts….. Space and dimension are bolstered by the quiet and greater contrast between, and around each bit of sound. All the small incremental improvements add up to what is essentially art in the form of reproduced music."
