PS Audio Power Plant
Posted by: Mark Dunn on 30 August 2000
As some may remember for the old forum, my mains supply is a piece of poop and I've been on a quest to improve it. Naturally, I did the dedicated spur with dedicated ground and this certainly improved things but in a way it also highlighted the differences between good and bad mains days. What it boils down to, is that you can't polish a turd.
I had asked about the PS Audio Power Plants and Vuk said he, Steve Karlik and Joe Petrik (now believed to be 'squealing like a little piggy' somewhere in Kentucky) had tried a PP300 on a NAP180 based system but it removed the 'personality' from the music. It was labeled as the 'PS Audio Prozac Plant'. At this point, please note that PS Audio do not recommend the baby PP300 for any power amp applications.
Well, since last Thursday (8/24) I've been having a home trial of the PP600. This produces nominally 600W (peak 720W) of clean and stable 60Hz power. I have all my major components plugged into it (Armageddon, Hi-Cap, 250) and now its had time to run in a bit I thought I'd post my findings.
1. It's a terrific product! No more hoping the system is 'on song'. You get repeatable results every time. The sound/music quality is at a higher level than even a very good mains day.
2. It produces balanced power (nominally 57.5V on live and neutral lines) which reduces system noise significantly.
3. If you have a T/T with an A.C. synchronous motor you are in for a VERY pleasant surprise. My Armageddon/LP12 sounds disheveled (best word fit, I think) when plugged into the wall by comparison, - irrespective of where the other equipment is plugged into.
4. PR&T and dynamics are fundamentally improved. Also, all 'Hi-Fi' aspects (soundstage etc.) change for the better. It took me a while to get used to the abundance of extra mid bass and low bass detail and presence and I eventually had to re-tune the system set up as the previous set-up was 'voiced' for crappy mains. If you try a Power Plant you MUST be aware of this as I'd say there's a good chance you'll have a similar experience.
5. The build quality is excellent, as is customer service.

Keep in mind: My 250 has 'only' a 450VA transformer. Those of you with 135s, 500s or active systems may find this solution price prohibitive, although there is a 1200W version available.
