DirectStream Power Plant 15

Reference standard AC power delivery and protection

Built in Boulder
All units handmade to order in Boulder, Colorado

Purify, protect, regulate, and rebuild unrestricted new power from old. The DirectStream P15 Power Plant is the gold standard for safety, reliability, and high-performance AC power regeneration. The P15 improves micro and macro dynamics, audio purity, instrumental separation, soundstage width and depth, and lowers background noise for any connected equipment. The P15 is the successor to the venerable P10 Power Plant, a tireless performer faithfully powering thousands of high-performance audio and video system around the world for nearly a decade. The P15 has been completely redesigned from the ground up with three times lower output impedance, lower distortion, a new FPGA based DSD sine wave generator, and an improved level of performance never before attained by any Power Plant of its size. If high-performance audio or video is your goal, there’s no better foundation for any system than a Power Plant AC regenerator.

DirectStream Power Plant 15

Product Description

The DirectStream Power Plant 15 is the next generation of AC power regeneration. It features an all new analog power amplifier and FPGA based sine wave generator based on pure, clean, analog DSD (PDM).  The P15 has 5 separate regenerated zones, buss bar delivery system, and 1500 watts of pure regenerated power. From medium to large power amplifiers to the smallest pieces of source equipment, the P15 will work magic on your system’s performance. Expect far better micro and macro dynamics as well as a cleaner, lower noise background.

Don’t starve your music or risk damaging your equipment. A P15 gives you greatly improved performance and safety from just plugging into the wall socket and far better dynamics, bass and a much bigger, open soundstage than any power conditioner on the market. Why settle for anything but a Power Plant? Take one home and try it today.

Customer testamonial

Kent Tager

With the P15 I expected a nice jump like the P10 was over the P5. WRONG. It was not another move up in sound, it was transformational. Audio memory is a very iffy thing because there are so many factors that come into play, but I do not recall any change I have made in years, not even moving up in speakers, that has done what the P15 has done. The sound stage is so much bigger and so three dimensional, the detail is through the roof better without being brighter or more artificially detailed like some amps and preamps might do. It is both more nuanced and more powerful. The excitement of the music is so much more palpable and the sheer joy of listening to Jen Chapin and the Rosetta Trio, Fourplay, Fleetwood Mac, Mark Knopfler, Brahms, and the others that have been played since I got this new beast is way better. It took about 48 hours for it really to get going, but boy oh boy what it has done to my system is amazing/transformational.

After spending thousands on upgrading sources, amps, speakers etc, the biggest single improvement i have ever had was plugging everything into the P15.
Don’t care for all the numbers too much but know what my ears hear and am now a total believer that these Power Plants should be a must if you want to get the best out of your system.
