DirectStream P20 Power Plant

Reference standard AC power delivery and protection

Built in Boulder
All units hand-made to order 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.

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.
