PS Audio DirectStream Power Plant 15

Contact Us for Pricing and Availability

The DirectStream P15 is the second largest high-end personal power generating station in the world, next to the P20. It is the successor of the venerable P10 Power Plant relied upon by thousands around the world. The P15 is all new, based on the P10, but rebuilt from the ground up. It features an ultra-low impedance analog power amplifier, pure DSD FPGA based sinewave generator, larger power supply, and the lowest distortion ever available in a Power Plant. The P15 is capable of powering any size system and bringing forth all that’s possible from your system ensuring you get the same great performance every time you listen.

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.

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.

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?
