DirectStream P20 Power Plant

Reference standard AC power delivery and protection

Built in Boulder
All units handmade in Boulder, Colorado.

Demanding systems require remarkable power. The DirectStream P20 Power Plant is our finest expression of the art of delivering protected, pure, regulated, distortion-free AC power. With peak power levels of 3600 watts, no equipment can tax the mighty P20. Finally, your most coveted components have the opportunity to unleash their full potential, no longer hindered by dynamic drops in AC caused by the unavoidable resistance of the miles of wiring between you and the power station. DirectStream P20 regulates both long-term fluctuations and peak dynamic without deviation, ensuring a solid foundation from which to build a state-of-the-art system. Its low output impedance and unhindered AC delivery are equivalent to less than 50 feet of 12 gauge wire connected directly to your city power source without the connecting miles of wire, the many transformers, and the multiple neighbors weakening and contaminating your power. The most demanding music systems require nothing less than the P20.

This PS Audio P20 Power Plant is one of the most aesthetically appealing components to come along. I found its overall execution to be very elegant and efficiently accomplished. In my further explorations, I came to appreciate that the hefty P20 incorporates a number of finessed features with particular attention to user convenience. It is said that familiarity breeds contempt. In my encounters with the P20 that was certainly not the case…

I could not get over the very engaging ability of the P20 to handle midrange material where I would be drawn into the performance convincingly.
Additionally, the P20 had an impressive stability in the lower reaches of the spectrum that added firmness and established authority to the performance.
The midrange conveyed a convincing certainty that projected a sense of compelling intentness. This aura of immediacy often translated into sonic scenarios
where I was often drawn into a performance spellbound and engaged. And full of admiration. For me, this aptitude to completely capture my attention
is the strong point of the P20. The upper reaches were always free flowing, extended and airy and delivered with an urgency that excelled in dynamic expressiveness.

I have everything plugged into it and simply find our music to be more dynamic and alive. Greater separation and resolution…and all with no hint of harshness or whatever. No glare or grit. But, more visceral and, well... more overall engagingly so….Bass seems to go lower with a wonderful sense of tightness… or rightness, especially as evident from the subs in the Vandersteens. Slam and punch, texture and presence. Palpable as all get out, and, as I said, texture… oh man… where there is, there is... texture.

Simply put, we love the P20 and cannot recommend it highly enough. It not only gets you clean AC, it gets you stable AC at the voltage you want. I know there is more to go into here, that we are really only scratching the surface with the P20's options, but then I am at that point where I would rather listen to music then play with gear. Plug and Play.

Living in downtown NYC, the juice that flows from my outlets varies literally from hour to hour. Voltage spikes and sags have been measured with deviations that vary from moderate to, "That can't be right." [With my demanding Class A amps] I needed two P20s, along with the P15 to handle all the other components' power needs.

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.

The P20 and P15 series products connect live and reproduced sound in a way that cannot be achieved any other way if dirty power is a culprit, and dirty power is almost always a culprit. If you are planning to build a great system, addressing the very element that brings these inanimate boxes to life, these products should be a priority. Your music will thank you.

I loved the P10, but the P20 offered all of that and a lower noise floor with even better transient response on dense classical music passages (massed strings), percussion notes occupying the space between the lowest octaves and improved vocal inflection, never mind an even more effortless sense of breathing to amps and preamps. Throw in twice the number of output devices and double the power-supply storage of the P10 and upgrading became a no-brainer.

I'm no stranger to PS Audio's line of Power Plant AC regenerators. About 20 years ago they introduced their first Power Plant, the P300, and I was one of the first to purchase a unit…. when I connected my front-end gear into it I just about had a heart attack. Here was the sound I was searching for!

Would it be necessary to provide specifics on how my system sounded better with my system connected to the P20 versus how it sounded when not connected? I'd end up reciting a litany of audiophile approved characteristics, all positive, such as an increased frequency response in both the highs and lows, a more transparent midrange, greater attack, longer decay times, a larger, deeper, more detailed and more properly drawn to scale soundstage when appropriate, a sense of increased dynamics, both of the micro- and macro- types, and especially a blacker background. I think that last characteristic is one that I noticed most often when evaluating the P20, that the background of my system was completely silent. I had a tough time realizing whether my linestage's mute button was activated or not. Those with any type of experience using a high-end system will know that a black background can lead to all sorts of other positive characteristics, especially a system's inner resolution, dynamic and transient performance, and a perceived increase in the extension of its highest frequencies.

The new PS Audio DirectStream Power Plant 20 AC Regenerator takes what was good with those older Power Plants, and the engineers and designers seem to have been able to boost the performance of what seemed like simple devices (they're not) and make them even better!

How does the DirectStream Power Plant 20 compare, sonically, to the P10 Power Plant?... I did do some comparative listening. The P20 sounded noticeably better, in all the same ways: naturalness, detail, image precision, soundstage depth and width.

I’ve come to consider my PerfectWave P10 Power Plant an essential reviewing tool, less because of the improvement it makes in the sound—although that is, of course, important—than because it levels the playing field for the equipment I review, ensuring the same, high-quality power for all the components I compare. There's much to be said for those magical late-night listening sessions when everything sounds magical, in part because the AC supply is quiet. Assuming it's powerful enough and doesn't limit current, a well-designed AC regenerator can provide the same quality of sound all the time.

I’m gonna violate the prime directive and tell you to get one. You won’t be able to un-hear it, and you won’t be able to live without it. So be ready to pull the trigger when you take the test drive. Consider yourself warned. It’s that good.

Part Time Audiophile

Rafe Arnott

Tone, and timbre of instruments are spot-on, with wood-bodied ones in particular in possession of the proper scale, weight, and resonance that I associate with real acoustic guitars. Organ, and piano notes are mellifluous, and the slide guitar, and horn arrangements have a burnished, brassy flavor. Opting in to the P20, the already big, hip-shaking bottom end seems to swell in size, and weight, with a deeper tonal shading now coming through. Vocals take on a sweeping, more expansive quality to the air volume surrounding the physical arrangement of singers, and a more chesty composition to the character of the oral discourse. This was a scenario that continued to play out every time I listened to a track off Tidal, closed the lid on a CD, or dropped the needle on an LP: everything that was pulling me deeper into the listening experience, into the meaning of the artists intent through the recorded medium – be it digital or analog–was enhanced through the P20. If the P10 was helping sink me into the depths of the song, the P20 was like throwing an anchor, and chain around my legs as I sank down. It seems that with this latest (and largest) edition to the company’s regenerator line (a new DirectStream Power Plant 15, and 12 have been unveiled since I received the P20), PS Audio has taken everything I’ve come to expect, and appreciate from the P10, and improved upon it wholesale.
