A local audio guy what live in city bought PP2000. I visited him last night to see how it worked. He has the newest version of PP2000 that he was waiting for 3-4 months or so. His newest unit has output circuit barkers, run at least with 3 times le...

...I local guy that I know did buy 2 month back a new PP2000 and it was measured horrible - a pure faulty production and no quality control at all. The PurePower admitted that it was faulty production run and promised t...

I made the 543rd remodeling on the Opera room and move the video playback equipment to the new, I hope the last location. As I connected everything into PP2000 as it use to be (not PP2000+) but older not “Plus” version than I have some light MF buzzi...

[quote user="miab"]Adrian, can you confirm whether you were using cable with shielding or without? Like you I had the buzzing go away when on battery or without PP2000 in system. It became dead silent. Then with PP2000 back in system there was buzzin...

[quote user="Romy the Cat"]The question that I would ask what do not pile everything to PP2000? Why do you want to leave anything out of it. Do you have any problems with sound with some specific components?[/quote]My initial idea was to run just sen...

[quote user="Romy the Cat"] … The sound still a bit harder then I would like it to have… I do not find any sensible explanations.[/quote] I was breaking my head trying to figure out why the large caps shunted battery in PP2000 suddenly gave me chang...

First of all, guys, can you name your posts on more identifiable way?A few comments I would like to make. I heard that the new revision of PP2000 has fans that do not run at full speed all time but have the speed of fan...

[quote user="Paul S"]It is confusing, but the NEUTRAL is not only "referenced to ground", but in properly-designed components it is THE ground. If the PP2000 is a 120V device with a 3-prong plug, then it has 2 references to ground within its chassis,...

I usually do not cruse across DIY forums unless someone folks about me. Here it was - at some Russian DIY site they translated my article “6C33C survival guide” that made me to see what they have in there. One article from their site attracted my...

Although I will be looking how to make two-three PP2000 to be plugged in the SAME POWER RECEPTACLE and do not affect each other sonically but I have to note that it might be difficult to deal with. In this situation we are dealing with external power...

[quote user="steverino"] I'm not surprised at your disappointing results as I have experienced the same with a variety of power filtration or generating devices. Your surmise is correct that such devices work much more easily with AV equipment or com...

dont know if the posters comment was meant to sound negitave or positive about this thread and you. myself and countless others who use PP2000 because its performance and clean power is what our hifi systems love. PP2000 is delivering the power and t...

[quote user="Paul S"]Regarding your HF: Do you use a naked ribbon over 10k? If the PP2000 has worked for you, you might want to try it.[/quote]Well, I will try the PP2000 after I have finished evaluating the new 2A3 tubes. The EdgarHorn Titans use a...

Truly desperate scofflaws might find themselves so annoyed by the hum that they lift the PP2000 AC ground connection at the PP2000 chassis and run that unit's ground only to a dedicated ground (with a lower impedance, of course), ...

I ve had my PP2000 for more than a year now and could not be any happier with the job it does for the sound my system delivers. I emailed them last week asking about any updates to the unit. As of this time no response. I believe and my ears back it ...

[quote user="oxric"]Romy, can you tell whether PurePower have identified precisely what made your units to perform as they do and whether that is now a standard feature of their off the shelf units? I am sure many here who might still purchase their ...

[quote user="Paul S"] Many of the expensive power cleaners and regenerators claim that they do not limit current. None the less, many of these devices do seem to go into a swoon as current demands increase. We all remember the days when these d...

Considering that PP2000 isn't plugged into a dedicated line and that line can be shared by other electric devices plugged into the grid, I wonder if the hum noise is getting into the PP2000 not from the ground wire, but the neutral wire for some defe...

Perhaps the PP2000 doesn't like working with inferior equipment!It seems obvious but did you try running the PP2000 from different wall outlets ? I know it should't make a difference.R Weissman...

[quote user="manisandher"]I'm happy to compare the new PP+3000 to my old PP2000 and share my findings.[/quote]So, the PP+3000 arrived... and went pretty much straight back.As soon as I switched the battery pack on, it started hissing and emitting a G...

[quote user="Romy the Cat"]Another cool discovery is that the new PP2000 looks like inject back to AC line less dirt then they did before, but it might be coming from the fact that I run each unit at own dedicate line and each units is loaded 3 time ...

[quote user="Bud"]Yes. Their is a direct correlation between surge current and dielectric materials dielectric constant. The voltages in question are high enough to use a thick dielectric material and just as with the effective resistance of the capa...

[quote user="Romy the Cat"]Possibly that you are right but it might be something else. My last year unit did inject back to power line a LOT of dirt. I just measured my new fixed unit and I was VERY surprised the it out back to the wall significantly...

Eventually I got electricity-wise what I had in my old listening room. It turned out that the last straw that I was missing was Lavry ADC that was connected to ground of my remote switcher.

[quote user="Bill"]Have a hum through my center channel speaker, the SET amp of which sits directly in front of the pp200 about a foot away. It is not relaTED to the DC offset of the 2000 as adjusting that does nothing to the hum, and running th...

[quote user="Lx_"] Well, this is consistent with the behavior I have. I can hear electrical devices behind the PP, especially those of the switching PS type: computer screen, laptop charger, DSL box, printer, SAT decoder... Good luck finding electron...

[quote user="steverino"] Why do you think the improved sonics were related to the residual noise or more precisely the hypothetical delta of noise components from one day to the next? You were very non specific about what was better and to what d...

[quote user="drdna"]
I chose this for a sound most free from "graininess" which may change with PP2000. However, what is the rationale to change the impedence loading on the tube, from your perspective? As you know the Magnequest OPT has taps for 4,...
