[quote user="Romy the Cat"]The recent LX’s posts made me to think about the PP2000 buttery. He reports that his buttery got way weaken from 2009. I used my older PP2000 from December 2008 and my currant problematic “upgraded” problematic PP2000 used ...

[quote user="Romy the Cat"]
[quote user="drdna"] Exactly. Thus, it suggests a ground loop internal to the PP2000, doesn't it? [/quote]
In my view it is highly unlikely as a definition of loop itself implies two contacts to ground and PP2000 has on...

Well, I have post able a number of articles about different aspects of Purepower 2000 operation and sound. I could make a few more but I think it is enough for now. I would like to drop a few general observation and conclusion.
It was a good sign th...

[quote user="Romy the Cat"]I still doubt that you were, by the virtue of insulation transformer and ground, able to get what PP2000 gives but as you understand there is no ways, or even needs, to address my doubts.[/quote]Yes agreed, there's no need ...

[quote user="Romy the Cat"]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...

If you follow this thread and my successes and tribulation with PurePower regenerators than you remember that I had problem with sound running two PP2000 for right and left channels. So, I had everything, including my DAW plugged into on PP2000,...

Paul, I'm happy to compare the new PP+3000 to my old PP2000 and share my findings. The new unit has arrived in the UK from Canada and should be at my place this Friday.It's true, I didn't particularly like the sound of the PP2000 running from its reg...

Well,
I have to tell you, Meiko41 that I was pleased to see that a local guy got a new PP2000. I kind of on the verge to get another PP2000 and this was a good preview what newest state of the PP2000 is. Even it was very clear the with PP2000...

Will do if I can get a review sample.

Have purchased two of the units for evaluation, using them for right and left channel and sources. Have also been using Romy's unit for the surrounds. Each running at about 35-45%. Sound is phenomenal; best I've ever heard from my system. One problem...

[quote user="Romy the Cat"]Simply beyond any criticism. The Purepower bass was something that sold me on the very first unit in June 2007. The very first Purepower 1050 had the same type of bass. What kind bass? Well, if juts did not “improve” it and...

Since the PP2000 works in my playback a bit over two weeks I think it would be worth to mention the changes that I observed after two weeks.
The HF and upper mid region returned back. Not completely but most of it. They returned without mind-oppres...

Okay, today I hooked it up and have spend some time listening. The change in my system was very dramatic and positive. First of all, it seems suddenly like a good electricity day. The noise floor dropped out. The timbre of the music and the body ...

Using the PP2000 has been a very interesting experience. Immediately listening I am NOT struck that it is the most wonderful improvement ever, which I have said before is a GOOD sign. Usually the seductive sound changes are colorations that are enj...

Well,I did speak with Damian in Technical Support at APS, and he informs me that this effect is something that they have reproduced in their lab, but only with extremely efficient loudspeakers and certain power supply designs in the amplifier. With ...

Here are some shots of what the this new unit does. This is the wave right out of the wall. Boston’s South End.
This is the PP2000 with 30% load running plugged into the wall
This is the same as above only the full wave. Note the non-symmetric sh...

Bill, when you were at my place I use two PP2000 running together as at that time I did not discover the effect. I was running my MF at -2dB and my tweeter at -1.5dB. As now I use one unit and I return back my MF and HF channels to the level as they ...

I certainly have my hands full with those dams PP2000. As I least last night UPS lost one of my units I send to PurePower to repair. The shipment was insured but the saddest part is that it was the best sounding PP2000 of mine. So, I will not be get...

I separated my two of my PP2000 in my rack with 3 feet space and run everything from one PP2000 and both Milq power amps from another PP2000. I also routed the incoming power cords that that are far from each other and far from outcoming power co...
|

I was wondering what is coming out from PP2000 that makes one unit affect another. It might be radio and magnetic stray fields. Last night I took my gauss meter and was sniffing all around my PurePower regenerators. I was not able to see any signific...

I am I wondering if my dissatisfaction with my new ULF channel is not the problem of my but the problem of the new PP2000 lower bass.

at the time I start fine tuning of the ULF ...

Spend a few hour last night and have all the things connected and laid out in the way how I think would be “properly”. It turned out to be noise and elegant. I changed the location of the components to make the shorter paths for power cables and for ...

"or APS relented to finally diagnose and repair your unit"As a sidebar to my repair problems I must note that I did not have to pressure PurePower to repair my unit. They responded to the matter in a timely fashion. They arranged for UPS to pick up...

[quote user="manisandher"]Sorry Romy I can't help you - I've never heard of this before. But I'm certainly tempted to explore further now...(Incidentally, my new PP2000 will arrive tomorrow.)[/quote]You can Google the “Legally Slow Down Power Meter” ...

I would place my bet on common mode noise being carried on the safety ground long before blaming RFThe ground on the amp has been tried both lifted and present. I have reversed the AC cord using a cheater plug without effect. I have tried grounding t...

This is Romy's unit that he let me borrow.It does produce the cleanest electricvity I've heard in my system in over 30 years of trying.A new find last night: The one amp with the problem power supply transformer is buzzing at the same frequency as th...

Well, it is not really debating but “kind of” debating… A few days back I receive emails from guy who been using PP2000 for a few month. He informed me that very much disagree with my assessment of PP2000 contribution. He explicitly asked me do not p...
