DirectStream Power Plant 15

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 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.
The P15 includes 5 separate zones and 1500 watts of pure regenerated power, delivered to each receptacle through 1/4″ thick copper buss bars. From medium to large power amplifiers to the smallest pieces of source equipment, the P15 will work magic on your system’s performance. Only the very best high-end system around the world rely on the P15 Power Plant for protection, purity, and performance.
With your system powered directly from the output of the P15, dynamics and openness are breathtaking. New voices, new harmonics and a renewed sense of musicality are yours the moment the P15 starts up. This is one of the most important pieces of audio equipment you can own, building a firm and reliable foundation for your system that will serve you for years to come.
