Paul,
How about Plasma TV and MW? Any possible life expectancy shortage with an endangered species like the Pioneer Kuro running on MW?
Also why does the Power and Output % of the P10s measure lower with MW on the front panel display compared to the SineWave setting even though the PPs run warmer on the MW settings?
Thanks,
Bob
@nordicbob I don’t foresee any problems with TV’s at all. Most of them have switch mode power supplies and MultiWave is very friendly with those. Should help their visuals as well.
I am not sure why the distortion is lower. We artificially deduct the third harmonic from the THD Measurement system so you get the net result without it and it may be that by using MW, you actually get a reduction in THD because of the longer charge time. Not sure.
The Power Plant runs warmer, of course, because it’s delivering more energy in MW.
so if the DC goes up a little (which is what happens with MW) it shouldn't matter.
I measured the B+ on my mono block tube power amps.
With Multiwave off, I measure 424 volts on each amp.
With Multiwave on, I measure 406 volts on each amp.
Is what I am seeing normal? And if so, please explain the electronics involved. - See more at: http://www.psaudio.com/vanilla/discussion/comment/16580#Comment_16580
An explanation from Bob Stadtherr:
You are correct that the peak voltage is about 5% lower in order to maintain the same RMS value. However the softer wave shape extends the amount of time that the rectifiers conduct and charge the filter capacitors. This means the peak current from the transformer is lower, and thus the IR drops in the tranformer are lower. This offsets the lower peak voltage, but only under load.
The wave shape was chosen so that in typical equipment (with a constant DC draw) the lower peak voltage and the improved transformer efficiency just cancel out and the dc is about the same.
In a power amplifier, usually we see a slightly lower DC voltage at idle, and about the same with typical loads. When the demand on the amp is high, we usually see much less sagging of the DC voltages than with a sine wave input.
Another benefit of the extended charging time is lower ripple current in the filter capacitors. This reduces the internal heating and extends the life of the parts. - See more at: http://www.psaudio.com/vanilla/discussion/comment/16580#Comment_16580

The effects on our 60" Plasma TV are profoundly positive, at least with our Kuro. Before upgrading from a P5 to the P10, I was using our P5 with in our little HT system powering everything including our plasma TV. One day when my wife was at work I decided to pull the P5 out of our HT system and try it in my 2 channel stereo system. When my wife settled down that evening to watch one of her favorite TV programs she asked me, "What happened to the picture? It does't look as good as it normally does with that show." The Power Plants appear to lower video noise which results in a more saturated picture with greater gradations in shading with more vivid colors, particularly in darker scenes. Even though the picture is still good without the Power Plant, it is a little washed out sans Power Plant. Well, whatever the reason for the improvement, the effects of the Power Plants are not subtle with a plasma; at least with ours.

Thank for sharing Bob's explanation about the voltage. I have a digital voltmeter which shows a 2 volt increase with MW 5 and 6 more than with the SineWave setting.
If I decide on using one of the higher MW settings with my tubed preamp in our stereo, I will probably adjust the voltage of the P10 down a couple of volts to compensate to ensure that the tube life is not shortened.

A couple of years ago, I did a comparison of picture quality with my Kuro PDP-151FD using the Power Plant Premier and P5:
Video Quality Comparisons of the P5 and Power Plant Premier
The following screen shots are from a paused image from a Tivo XL High Definition digital video recorder. The program was a CNN high definition (1080i) news broadcast. The native resolution of the Pioneer Kuro high definition plasma is 1080p (1920 x 1080 pixels). The pictures were taken with a Fuji Finepix S9000 9 megapixel digital camera. The camera's image resolution was 3488 x 2616 (9,124,608 pixels). Figures 35, 36, and 37 are reduced-size versions (800 x 669 or 535,200 pixels) of the original screen shots for faster page loading and are 1/17th the size of the original. It is easier to see differences in figures 35-37 and in figures 38-40 if they are downloaded and viewed in succession.
Screen shots were taken with the TV plugged into an ordinary household outlet, with the TV plugged into a Power Plant Premier (PPP) AC regenerator and with the TV plugged into a PerfectWave P5 AC regenerator. In each case, the power cord between the TV and power source was a PS Audio Statement SC. The Power Cord between the AC regenerators and the wall was a PS Audio AC-5. The wall outlet for the AC regenerators was a PS Audio Soloist SE in-wall conditioner, which terminated a dedicated 20 amp AC circuit. The PPP had been in use since 2008. The P5 was new with 100 hours of use.
The image with the PPP was more detailed than that from the wall outlet, but it was also darker, which indicated some current limiting by the PPP. Notice that there was no apparent current limiting with the P5 as the image was equal in brightness to the wall outlet image.
Figure 35. Screen shot of HDTV image with TV plugged into wall outlet.
Figure 36. Screen shot of HDTV image with TV plugged into Power Plant Premier AC regenerator.
Figure 37. Screen shot of HDTV image with TV plugged into PerfectWave P5 AC regenerator.
The cropped images below of the news anchor's left eye provide better insight into picture quality improvements going from the wall outlet to the P5.

Figure 38. Crop of news anchor's left eye from TV plugged into the wall outlet.

Figure 39. Crop of news anchor's left eye from TV plugged into the Power Plant Premier AC regenerator.

Figure 40. Crop of news anchor's left eye from TV plugged into the PerfectWave P5 AC regenerator.
Comparing the PPP cropped image (figure 39) to the wall outlet cropped image (figure 38), lower power line noise resulted in a smoother picture (less pixelation or "blockiness") and less smearing of pixel information. The three studio light reflections above the news anchor's pupil appear as three blobs of light in the wall outlet cropped image. The studio light reflections in the PPP cropped image are much sharper, more detailed and rectangular than the wall outlet image. There is less pixelation in the eyebrow. The curved edge of the iris is smoother. Notice however, that this increased detail comes at the cost of decreased light output. The PPP image is significantly darker than the wall outlet image.
The P5 cropped image has the same level of brightness as the wall outlet cropped image (no evident current limiting) and more color and shadow detail than the PPP cropped image. The curved edge of the iris is smoother than in the PPP image and much smoother than in the wall outlet image. The shapes of the individual bulbs of the studio light panels are more rectangular and the spaces between bulbs are more sharply defined.
The differences in light output, color rendition, clarity and detail among figures 38, 39 and 40 provide insight into why the plasma television picture was much more three dimensional, vivid and lifelike when each and every pixel was not distorted with significant amounts of electrical noise.

Wow, this is awesome!! What a lot of work. This is great stuff and love to see this.
Spread your wares to other forums. The stuff you have works very well Paul.
Other manufactories have there own threads to stimulate discussion that will lead to sales. You should some of the stuff people push and your is way ahead of all of them.

@ Paul,
Just downloaded the new P-10 Firmware. I waited until all the bugs were out!
All I can do is thank you and Dennis (and whoever else was involved) for a brand new P-10! It has really added some magic to the system.
Thank you!
Thanks to you for trying and posting to the community. The credit goes first to Bob Stadtherr, our chief engineer who created the new version and then to Dennis for programming it into the machine. Me for smiling a lot as I listened.
Does the six steps has effect when the P10 is on the sine-wave position?
No, only in the MultiWave position.
This seemed the best thread to post this observation in for the latest P-5 -10 update.
If I’m in sine-wave mode my noise harvesters flash way more often than when I’m in MW level 6, I’m interested in any comments on this?
now I do have SMPS600 and NCORE 400 amps
I recently purchased a powerbase and have only trialled it between the wall socket and the P-5 at this stage I’m looking forward with interest to hear how it goes with the one way gate filter of the powerbase between the SMPS600 and NCORE 400 amps and the P-5

DarqueKnight,
Thank you for your diligence and great work that you did for your comparison. Although, my wife quite accidentally discovered the benefits of our P5 on the PQ of our Kuro, I had quite unexpectedly found these same improvements back when I owned a PPP.
There are plenty of “Flat Earth” people out there that would laugh at anyone for even suggesting that AC power could have an effect on the PQ of a TV monitor as evidenced on a popular AV Kuro forum. A poster on that forum who stated that his PS Audio Regenerator made the picture of his 151 Kuro Plasma better was ridiculed and laughed at by those who had no experience with any of the PS Audio products on their beloved TVs. Perhaps if they had of found your evidence with pictures, they might have second thought? Well, maybe not?
:-?

I always laugh at people who scoff at technical concepts without possessing any relevant knowledge or experience. Condemnation without investigation is the height of ignorance.

Having a second thought requires thinking. Thinking is anathema to the Internet troll's life philosophy.
I did a quick post regarding ps audio p10 and p5. I did get quick ridicule
But not just from users like me but also from so called industry people
And odd enough someone who makes line filters with giant ferrite
Tubes inside and sells them for about about 4 k.
And best of all the power does not pass through it it just connects in the outlet strips he also sells for 4 k.
And here Paul’s product does work and has plenty of details about how it works. Rather than obtain a patent that doe sent really say anything special.

The Power Plants do put noise back on the line. I have not noticed a difference wit NHs, but will need to experiment.

I am not a video person, but do not serious home theater people tweak with cables, good grounding, etc. in addition to setting up their monitors with a colorimeter? Power seems a likely contender.
@elk and anyone interested in
I just find it interesting the NH flash (pickup noise when sine wave is selected and not with MW) and some prefer the sound when sinewave is selected, be that what it is.
I have been hugely excited about the benefit of having a Powerbase in my system purchased after the Christmas while on holiday, also the awesome new firmware for the Power Plant - is just fantastic. Adding a powerbase to my system was huge too, the musicality and tone of my system now is the best yet. I thought I had a good sounding system already. Now the illusion I hear is the most believable and closest I have had the fortune to hear live shows. Thanks so much PS Audio :x
