PS Audio new P15 vs older P10 Power Plant review

Recommended Posts

A side-by-side comparison was made between the new P15 directstream Power Plant regenerator and the older model P10. Both power plants are the same size & shape, have the same number of outlets, and nearly the same features and capacity. The P15 has a number of technical updates that steps up performance even further.

- so in this comparison we are comparing apples with apples -

 

The P10 was formerly their top model, but above the P15 is a new top model the even bigger P20  identified by front handles, an increase in height, more AC outlets than ever, and much heavier. 

PS Audio (USA) power regenerators are top notch with a sound improvement similar to adding a new amplifier to your system.

 

 

Comparison overview - With the new P15 feeding CD, DAC, preamp and monoblock power amps (all via Valhalla2 power cables) there is a small initial sound difference and this is noted by a refinement of sound, with musical notes of more subtlety and clearer expression. Opinions are based on 0 to 50 hours on the P15 and it kept improving during ownership.

Explaining further - with the older P5/P10 regenerator one of the traditional sound virtues is a very solid leading edge to notes (no power supply sag) and this gives impressive impact, as well as being fast. 

The P15 is slightly less obvious in this impact, but it seems less is more, as the surrounding and expressive background nuances are more developed and flow out easier. 

 

BASS test difference - An example is from the CD ‘Best of Sade’ track 15 ‘Cherish the Day’ that has 2 bass levels as the song progresses and some good drum pitter-patter;

With McIntosh 601 monoblock power amps, I swapped over only the power cords (x2) from the older P10 to the new P15. - The BASS notes on the P15 go a bit deeper, and also the P15 is more neutral in low frequencies with a bit more surrounding information. 

Comparatively, this seems to indicate a bit of BASS compression with the older P10 regenerator. 

 

 

MIDRANGE and HIGHS test difference – I chose a CD by John Lennon ‘Lennon Legend’ track 17 ‘Borrowed Time’ – to me a sweet test track. 

(Technical – power amp cords swapped back to P10 again);

Using a Soulution 725 solid-state preamp, only the power cord was swapped in from the P10 to the P15, and I noted the music was smoother on the edges. I then additionally swapped in a PS Audio Directstream transport and DAC to the P15, and it was similar again, so the difference overall was an easier listen in the midrange and treble noting better resolution of the tish-tish on cymbals with drumsticks.

 

 

GENERAL LISTENING COMMENTS - On music that has a lot of ambience, the P15 delivers an enchanting and smooth sound that reveals echoes and subtleties. This is particularly evident on the album by ‘Lorde’ (NZ band) with album ‘Pure Heroine’. Nearly all the tracks are a good listen, with great bass on Track 3 ‘Royals’, and Track 9 ‘White Teeth Teens’ was a good listen after some familiarity.

Regarding sound stage width, depth and height, it didn’t jump out as being obviously different between the P10 and P15, so the older P10 can still hold its head high in these important areas. 

 

I will admit the sound system with the P15 sounded the best yet on interesting albums such as The Flaming Lips - Yoshimi Battles the Pink Robots; INXS, War on Drugs - a Deeper Understanding; the Cure - Disintegration.

 

In a blind test with say some listening fatigue after an hour going back and forth, I feel it would be a challenge to reliably pick the Power Plant regenerator in use as its not night and day change, even though there is a difference in favour of the P15 with subtlety and nuances and an easier music flow.

 

 

Chassis / Casing - the setup and features are much the same, but there’s a bit of difference as the P15 touch screen is even bigger, has sharper text, and a feel closer to touching glass. Comparatively, the P10 has a more traditional liquid crystal touch screen. 

One new setup refinement aid is an ‘auto tune’ button for Phase Tune. Previously you had to listen hard to determine a best number between -10 and +10, so now by pressing the ‘auto tune’ button its easy – the unit selected -4 most times I tried it. 

The rear of chassis is functionally the same, but has layout improvements such as the 9 outputs being mounted lower down on the chassis. 

 

In summary, we are talking say a 5-10% difference centred around the system being easier to listen to with improved clarity, resolution and transparency of the P15 that grows on you as the hours clock up. You can turn the volume up more on your favourite tracks, and edgy recordings are an easier listen. Being easier on the ears is a very desirable benefit especially in an ‘all solid-state system’. And yes, I bought one.

For people that haven’t experienced the older P10 it’s still a seriously good power regenerator, and such is the demand I sold mine within 24 hours.

Thank you for the comparison review, looks like I’ll keep my P10, doesn’t seem to  be enough improvement to justify the cost of upgrading.

Might be worth reserving judgement until OP's P15 has more hours on it.

Hopefully he will post again in the near future with an update....?😉

COMPARISON UPDATE - Being the original thread poster, maybe I'm a hard marker, but the original thrust of the comparison article with the new P15 vs older P10 regenerator still stands. Yes, the new P15 is very good, and with hundreds of hours on it now, maybe up to a 20% improvement over time as the refinements are appreciated. Percentage figure wise, it really depends how an individual measures/rates subtle changes.

The older P10's reputation still stands very high as it will always be a game changer for people wishing to experience the clear audible benefits at a cost saving by buying 2nd hand.

I've read overseas reports where they think the update is hugely different, including PS Audio advertisements, but the reality is it's an incremental refinement over its predecessor, based on updated electronic design, parts selection and control processing. And this is always welcome.

As I often listen to equipment in shops it's a noticeable difference when the power supply is not treated, eg. subtly annoying on the ear - but with a recent exception - an American VTL tubed pre and power amps driving the big UK Tannoy Canterbury gold reference speakers, now that was heaven.

Great input Anthony. I use the P10 with the main aim to keep a constant 230V running through my equipment. Have you gone back to wall plugs to hear the difference without the regenerators??

Wall plugs answer - There’s no going back .... Typically equipment with reasonable transparency will sound less energetic from a wall socket especially noticeable on initial strike of a note, and after you get a handle on things you will notice a noisier background.
That said, when most/all components are plugged back into a regenerator or equally well a quality filtered product, the whole tone of a system goes up quite a notch and is far more enjoyable as you will be able to follow individual instruments much easier. Hence why myself and others say sound wise it’s like connecting in a new amp.

You might have experienced a similar effect with above average equipment using a standard power cord into the wall, and then you plug in a HiFi special.
By comparison a standard cord can be unlistenable due to a frequency mess even to the point of not wishing to turn it back on. I experienced this a while back with a Mark Levinson amp that demanded a HiFi special - it showed me the weak link.
However with a friends Cambridge stereo amp I tried out a Nordost Valhalla2 power cord expecting a massive improvement but alas it was 10% better and this indicates at least the amp had a very good power stage design.
On a Krell 400xi stereo amp the V2 power cord improvement was 80% better.
So the level of improvement/effect is equipment and listening space dependent.

@Anthony1 Just wondering if you have had experience with changing fuse in the PS Audio (either P10 or P15).

I've tried playing with a few fuses in my P10 and all resulting in slightly different flavours.

That's @cyberkank for bringing this up.

 

I'd also be interested in experiences with changing fuses on the P series range of Power Plants. There are two on my shortlist:

  • Synergistic Research orange fuse (will be released in about a week or so)
  • Audio Magic Ultimate Beeswax SHD

@Anthony1 thanks for your very comprehensive and informative comparison of the P15 vs P10.

Only the very finest high-end system around the world use the P10 Power Plant and this is the piece to strive for.
       
      Description
      UNIT WITH AUSTRALIAN RECEPTACLES
      We’ve learned as an industry over the 50+ years that high-end audio has been evolving is: that power we buy is none-too-reliable, and unfortunately far more often than not, very poor quality. The PS Audio Power Plant is an affordable reboot of that limitation – using the supplied power only to run, it provides a stable and near-perfect AC sine wave, freeing up your components to do their best work. It has been called the single most important piece of equipment in an A/V system. With a PS Audio Power Plant as the essential building block, your system will always be able to perform at its best.
      At the PerfectWave Power Plant 10’s core, an internal high current analog amplifier produces ultra low distortion, ultra low output impedance, and highly regulated new AC power for connected equipment. Sine wave enhancement technologies from the P10 including MultiWave and CleanWave provide unparalleled control of the Power Plants for hands-on control settings for optimum performance, system specific. The PerfectWave Power Plant 10 delivers up to 1250 watts of continuous power and 70 amps of instantaneous current delivery.
      Our new network technology on board provides unprecedented control and monitoring of all your connected devices.Automatically reboot routers, modems, and network devices when Internet dropouts occur. Schedule devices to power on and off automatically optimizing power consumption in your system. Receive emails automatically when power occurrences occur, as the PerfectWave Premier P10 is automatically reacting on it’s own; all made possible by PS connected technology and PS Audio’s unique Globalnet servers.
      Once your system is powered by a P10 Power Plant all you or you need to do is go to the web through any web enabled device, including a Blackberry or iPhone, and access the P10’s control panel if you wish. From the P10’s control panel any connected equipment can be rebooted, turned on or off, or have its status checked. It’s that simple. The P10 will monitor your power line quality and report any problems to you through the web page, text alerts or emails sent anywhere you wish. It’s up to you. The P10’s real-time and on-line measurement system includes surges, voltage levels, power usage and power quality as measured by THD (Total Harmonic Distortion) on the line.

      Present at the shootout were SNA members Tuyen, 24Bits and myself and it was conducted in Chanh's excellent man-cave. Apologies for the lack of photos but Chanh kept the red wine flowing, and you know the rest!
       
      The contenders were  -
       
      PSAudio P10 - Price - around $6300.  This unit uses PSAudio's patented technology to regenerate power.  Power efficiency is now at 85% and the unit is passively cooled.  It is microprocessor controlled and  has the ability to regulate voltage.  The screen provides relevant information including THD of incoming and regenerated power, power consumption etc. It can provide dynamic power for attached appliances totalling 1200 watts. This means that provided the average power draw is 1200 watts or less the P10 will keep up with sudden power demands for transients etc.  The power output THD is less than 1% .
       
      AG1500 - Price around $1k delivered to Australia. The AG1500 is an online double conversion power supply which regenerates power in a different manner to the P10. The P10 is essentially an amplifier whereas the AG1500 converts AC to DC and then DC to AC. This process should eliminate power impurities  however the dynamic headroom is limited by the size of the inverter. In this case it is 1500VA which translates to less headroom than the P10. 
       
      Airlink 3KVA  Balanced  Power supply - Price around $1k landed in Australia. This unit is essentially a very big isolating toroidal balanced mains transformer.  For a 230V power the unit  divides the incoming current into 2 x 115 v out of phase signals. i.e. 2 Live wires are inversely phased centre tapped to earth. When combined the equal and opposite currents are cancelled out  i.e. common-mode  rejection. The units can be purchased in sizes up to 15KVA and Airlink are open to special requests.  At 3KVA rating the unit can be operated up to max capacity but dynamics start to suffer if operated above 50% loading which gives it similar dynamic headroom to the P10. Being a passive device, there isn't anything really likely to go wrong with the unit  so reliability shouldn't be an issue like it has been with the P10.
       
      The unit tested is bog standard without any additional filtering ( optional extras) but with 20V lower output than input. This is intended to deal with consistently high voltages seen in my area - around  250v
       
       
      RESULTS
       
      Testing commenced around 8PM when the power was much cleaner and more stable than during the day. However, quite dramatic improvements were detected against the standard wall power even at this time of night.  The average total load was between 500 and 800 watts depending upon which power  amplifiers were used. Each unit is discussed below in order of its performance ranking:
       
      1. P10  -  With the P10 dynamics improved noticeably,  as did resolution, imaging and tonal quality. This is a major upgrade to any sound system that does not have decent mains conditioning in place. We noticed THD levels going from 3-5% on input down to 0.8%  which could in part explain the  much higher resolution we were experiencing. The soundstage was more expansive and imaging was more 3D like. The P10 was clearly the best performer.
       
      2. Airlink Balanced & Isolating Power Supply - This unit matched the P10 in all areas except ultimate resolution.  Like the P10, dynamics improved markedly. The soundstage opened up and  imaging was more 3D like and there was an improvement in resolution but not like that of the P10. The overall tonal balance was  a bit warmer than the P10.  Depending upon your point of view,  The Airlink balanced power supply could be seen as being between 80% and 90% of the P10 performance.
       
      3. AG1500  - With this unit, sound improvements were detected when compared to the  raw mains power but nowhere near that experienced with the other two. However, even with a relatively light load and volume settings, dynamics suffered noticeably. It seems that the AG1500 should not be used with power amplifiers if you want to preserve the full dynamics of the music.
       
      Ultimate Combo:
       
      We then fed the output of the Airlink transformer to the P10 and got the best results for the night. There was an incremental improvement in all aspects of the sound with the warmer tonal balance of the Airlink being combined with the high resolution of the P10.
       
      Bang for Your Buck:
       
      Airlink - With this in place the system sound improves by a significant margin  for a reasonable price . Please note however that coming from the UK they would have UK, or Schuko  fittings.  
       
      Tuyen's Opinion 
       
      Tuyen provided some thoughts by PM and these are repeated here with his permission:
       
      "Yep, P10 is winner in terms of reducing THD levels, hence allowing for a more quiet background. More nuances of the music comes through. Gives a greater sense of dynamic range. Didn't restrict dynamics in any noticeable way.

      The 3kva airlink balanced transformer surprised me some what. It quietened the background (but not to the same level as the p10). It made the music sound fluid/refined and relaxed. No problem with dynamics. Didn't clean up the THD in the line, so compared to the P10, I felt it did not expose that '1-2%' of micro dynamics/detail, that the P10 allowed through. From experience, that relaxed/naturalness could be partly due to the drop down from 240v to 220v as Tasso did mention his unit does drop the output down 20v.

      The AG1500 while providing an improvement over going straight from wall socket, in terms of slightly more detail, refinement and image separation, it compressed the dynamic range a bit, causing the music to sound flatter/less 3d presence. Did not have as black background as the p10, so those nuances(which can actually be important in the well recorded music we were listening to) don't get fleshed out. Performed the worse out of the 3 on the night.

      What then became interesting was when we decided to hook the P10 into the airlink,  I felt it provided what seemed to be the best of both worlds. The airlink allowed for the P10 to work less hard maybe? Either way it provided a more rounded/natural/fuller/fluid sound compared to running the P10 alone. Don't understand the reason why, as the idea of a regenerator is to remove all effects of the incoming power.  But alas, It was what my ears say it was 


      Now, I must look into one of those 240-220 airlinks. The power at my house is usually 250v, so a 20v drop will set it at a healthy 230v. The AG1500 might be good to experiment with just powering things like my laptop, maybe dac and crossover. Power amps maybe go direct from an airlink.


      In saying that, P10 was the pick of the night. So it should be for the cost of a unit!

      Great night. Thanks Chanh. Hope you got home safely Tasso?

      Catch up again soon"
       
      Yes, I did get home safely and thank you again to Chanh for hosting the evening .
