I have owned this Power Plant from new. It betters all the other ways of removing noise from the mains. Easily handled my entire system including a big valve amp. It converts the AC mains to DC, smooths it and reconstructs a purer AC signal. So in effect the mains power starts in your room.
Essential in these days of digital noise on the mains. Why waste money on a separate filter for each bit of kit?
Like all my stuff, its in great condition and has had little real use. It comes with original box and packing.
