PS Audio's P5 Power Plant along with their P10 are the finest ones they ever built, and the best two on the market today. There are so many great features and benefits offered by these that I recommend viewing PS website for a full description.
If you think about it, everything you hear in an audio system, or see in a video system is built on AC power. Once you hear and see these benefits on your own system, you will never want to do without one! These will dramatically improve the picture quality of your TV, deeper blacks, depth, more vibrant colors yet natural skin tones, etc. Same for audio, dramatically improved dynamics, openness, transparency, less fatigue and I could go on but your get the point.
I learned years ago these benefits and enjoyed the previous generation Power Plant Premier. The P5 was a rather dramatic improvement over the PPP as noted by PS Audio. Very little use, still like new, warranted. At this low price, my price is firm and shipping is not included. Thanks for understanding and appreciation of what a great value this is at this price! firstname.lastname@example.org
