Stellar Power Plant 3

Generate new AC power for best performance

Built in Boulder

The Stellar Power Plant 3 stands on the shoulders of giants. Built as an evolution from our renowned P12, P15, and P20 the P3 is our most affordable regenerator – perfect for powering sources and small to medium systems. Power Plants generate sine-wave-perfect, regulated, high current AC power from your home’s AC. In the process of regeneration, problems on your power line such as low voltage, distorted waveforms, sagging power, and noise are eliminated and the power quality enhanced. 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. You can feel 100% confident that a P3 will provide pure and safe power under any condition.

Stellar Power Plant 3

Product Description

Providing 300 watts of continuous power output and peaks of 900 watts, the P3 is the perfect companion for source gear and systems running high efficiency Class D amps like the Stellar M700 monoblocks. Designed with elegant simplicity in mind, the P3 is a plug and play device that will provide you with perfect power without any fuss.

Power Plants are regarded for their ability to reduce noise and THD to virtually zero while providing rock steady voltage output. Traditional power conditioners can only affect a portion of incoming noise and are unable to compensate for over or under voltage. Furthermore, power conditioners raise the impedance of the power going to your system, which can bleach your sound and drain away dynamics. The P3 handles things completely differently. Through the P3’s active regeneration process, it is able to provide perfect power while also lowering the impedance, increasing the dynamics and openness of your system.

Best of all, the P3 features overbuilt surge and spike protection, meaning you can rest easy knowing your system is safe.

Don’t starve your music or risk damaging your equipment. A P3 gives you greatly improved performance and safety from just plugging into the wall socket and far better dynamics, more authoritative bass and a much bigger, more 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.
