DirectStream Power Plant 12

Generate new AC power for best performance

Built in Boulder
All units handmade in Boulder, Colorado.

The DirectStream Power Plant 12 is the successor to the venerable P5 Power Plant. The P12 is 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. Power Plants take your incoming AC power and regenerate 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 results are both audibly and visually stunning when powering either audio or video products. Further, the level of protection afforded connected equipment is extraordinary. Feel 100% confident that a P12 will provide pure and safe power under any condition.

DirectStream Power Plant 12

Product Description

The DirectStream Power Plant 12 features an all new analog power amplifier and FPGA sine wave generator based on pure, clean, analog DSD (PDM). The P12 is our most powerful compact regenerator with 1250 watts of pure power. From medium to large power amplifiers to the smallest pieces of source equipment, the P12 will work magic on your system’s performance. Dynamics and openness are breathtaking with the P12.

This is clearly one of the most important pieces of audio equipment you can own. 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 P12 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 passive power conditioner on the market. Why settle for anything but a Power Plant? Take one home and try it today.

As good as the system had sounded with the P5, with the P12 there was a major step forward in overall realism. With no change in volume setting, the sound was more dynamic. This was particularly noticeable with audiophile blockbuster CDs….

In my initial bout of listening, amplification was provided by the PS Audio Stellar M700s, and as it's likely that PSA "voiced" those amps with a Power Plant in their reference system, the P12 and M700 might be expected to act synergistically. And might it also be that amps with a class-D output stage, such as the M700, are particularly sensitive to the purity of the AC, but that this would not be the case with amps of very different design—say, my own McIntosh MC275 LE?

The improvement wrought by the P12 was, if anything, greater with the McIntosh. The midbass-to-low-bass region was clearer, with bass drums and timpani seemingly having a more solid foundation, and transients generally having crisper onsets and more rapid decays.

I know PS Audio is doing things differently, and I had a basic grasp of the technology, but the deep, inky darkness coming from my system was quite unnerving. Once heard, it’s difficult to forget. This non background, in conjunction with some superior cabling, allowed hyper details into the gulf that was the soundstage.

One thing did surprise me. How do you make a four thousand dollar headphone amplifier sound better? Well, give it a clean sine wave source of power…. even the Pass Labs HA-1 was improved with the DirectStream Power Plant 12’s regenerated power, and that caused me to spend way more time listening to my headphones than I probably should have.

Overall, I think the DirectStream Power Plant 12 enhanced the quality of my systems without changing the nature of them. I used both aftermarket and generic power cords, and while there was a difference in sound with each power cord, the overall improvement of the system could not be doubted….I recommend giving a DirectStream Power Plant 12 a listen.
