I’ve listed this short review of the PS Audio P10 Power Regenerator under ‘Things That Annoy Me’, which, if you’ve been paying attention, you’ll know that this category is reserved for stuff that I’d rather not have to have, but now that I’ve heard it, I can’t live without.

I’ve owned PS Audio power gear in the past. The PS Audio P600 power-plant was a hunk of metal with blue LEDs that did nothing whatsoever for the sound of any system in which I used it. I chalked this down to being in semi rural locations where the incoming AC was probably OK to begin with, so the P600 didn’t really have a lot of work to do. I sold that unit almost a decade ago and I’ve been regenerator free ever since. Until now that is.

In my new home I’ve been toying with the idea of improving power delivery to my system by running additional AC lines. I have one circuit dedicated to the listening room but it supplies 3 outlets, each of which has some piece of audio gear hanging off it. Running new lines was going to be a saga, crawling under floor space that’s home to things with too many legs and other ‘S’ shaped things with no legs. There had to be a better way.

The PS Audio P10 arrived via FedEx in a smaller box than I’d expected. The weight of the box was actually quite manageable, unlike the similarly sized Edge NL10.2 power amp I’d shipped out to a new owner a few weeks ago.

Setting up the P10 was easy. Plug it into the wall and plug things into it, and voila, you’re good to go.

It does have isolated outlets for high current gear like power amps and multiple zones you can use to split up analog from digital. This was useful in theory and gave me a warm and fuzzy feeling as I was plugging in the big ARC Ref with its KT150’s, adjacent the power supply for my Origin Live Turntable.

The PS Audio P10 has various new features and technology over its older cousin the P600. One of the features I was interested in looking at was the actual measured sine wave of the incoming AC supply. I live in an old 1900’s farmhouse and the nearest neighbors are a good half mile away as the crow flies. I have my own pole mounted transformer a stones throw from my listening room, so, I’d decided ahead of time that the AC would be strong and clean and the P10 would be another colossal waste of dough. And I was half right.

Switching the unit on and scrolling through the various screens I found the incoming AC waveform and sure enough it looked bloody perfect. I mean it was just super clean with only a tiny little flat spot on the peaks. It held steady at 109.3v and couldn’t have been prettier. So I powered up the rig and stuck in a CD to get things warmed up then went off for dinner.

I ain’t gonna use terms like ‘my jaw dropped’ or ‘I was blown away’ ‘cos I’m British and far too refined for any of your blue-collar vernacular, but when I sat down for a listen there was a jolly good improvement in the sound of my system old bean. I figured part of it was the dismantling and unplugging of power cords and re-routing of the cabling to reach the P10. That would provide positive attributes, from the wiping of connection pins while unplugging and re-plugging cords, and negative attributes from disturbing the position of power cables. I figured a horse a piece and decided that things did indeed sound better, but that I’d need to assess the changes over a few days to be sure of what I was hearing.

Well I can honestly say that the P10 makes a worthwhile improvement in sound. More than anything else it seems to reduce the noise-floor considerably, adding to the overall transparency of the system as a whole. I believe the two frequency extremes are also enhanced. The bass feels a few notes more extended and the treble has acquired a new level of airiness and sparkle, all without any sense of grunge. The grunge removal gives a sense of improved dynamics and slightly improves the imaging ability of the system. Naturally these comments relate to the system and not to individual components. It could be that taking the power amp off the P10 and going straight into the wall could yield another sonic improvement to the system as a whole. But as of now I haven’t tried any of the weird audiophile dances and rituals that pertain to the arrival of a new piece of kit.

So good for you, PS Audio. You’ve built a device that I shouldn’t really need and now I’m stuck with it.
