Yes, the remove the battery pack will lighten it considerably as it has more butteries. The PP3000 runs from 96V instead the 72V of PP2000. With all simplicity of butteries removing I do not want to do it as I would like do not go into the units. Also, it kind of funny but I do have a dolly but I never used it with audio equipment. It just did not “click” to me that moving a pile of household crap in basement is not the same as to move dam heavy PP3000. Anyhow, I was able last night to defeat my laziness and PP3000 is semi-operational now.

PurePower 3000 vs. PurePower 2000
fiogf49gjkf0d

It is mean rainy day today in Boston and I’ve been playing with my new PurePower 3000 regenerator. It has been a bit bumpy as there was a frustrating issue, that looks like a shipping damage, the PurePower guys promise to fix it.
My initial sentiment from yesterday was that PurePower 3000 has a different sound then PurePower 2000 only got more conformation and more evidence today. In short: PurePower 3000 do sound better then PurePower 2000, in fact it even measured better than PP2000. If I were an industry-plugged reviewer then I would try to convince you to sell PP2000 and to get PP3000, I am sure the PurePower people would love it. However, since I do not give damn what you buy or use you need to understand that my comments only about sonic differences I observe. Furthermore, I am not sure that the sonic advantages of PP3000 are because it is “better”. I comment upon the observable differences, hot to interpreted those differences is a bit more complicated subject. I not always have the explanation to myself, if you do than good for you, share them with me and I will tell you why you are wrong.

1) PP3000 is heavier than PP2000, looks like the same side and looks like not much heavier in specification but it is much more pain in ass to move it.

2) PP3000 has more noise from fans than PP2000.  It is “fanyer” sort of speaking. It is absolutely not bother me as my PP3000 sits good 25 feet away from my listening position. If it was sitting right next to my chair with 3-5 feet then it might be an issue I guess. I think it is because the fans in the unit are sucking intake air right from the holes atop the front panel. If PurePower would put one surface between the fan and hole, creating sort of labyrinth for incoming air then it would kill the noise significantly.  Nevertheless, the severity of the noise is not too critical and if the unit good 10 feet away then it is not a problem at all.

3) The signature of PurePower “fuzziness” atop of the sinusoid that that I been reporting on all PurePower unit is there but it measured the best that any another PurePower unit I had. The amplitude and the spread of the fuzziness is very consistent, lower than with any other PurePower unit I measured it and the most important the it is practically identical between unit runs on battery or from power lines. None of the former multiple PP1050, PP2000 that I experimented with did not have this last characteristic.

4) DC offset adjustment. PurePower still use that ridiculously-manuals DC offset destroyer that I very much disagree with them. However, it looks like it works with PP3000 better then with PP2000.  With PP3000 in the best DC offset setting I get lower noise in my toroids then I had with the best setting using PP2000. With both of them I have them practically silent but with PP3000 this definition of silence is literal. You need to understand that level of my anal-retentiveness and demands is much higher than any normal person would demand. I do not even measure DC. I usually take doctor stethoscope and press it against the toroid that feeds Melquiades amps with B+ for output tube. Then I spin the DC offset on regenerator unit I have minimum noise in stethoscope. With PP2000 I had very fine residual noise (not in room but in stethoscope). With PP3000 I have practically no noise at all (in stethoscope!)

5) With all playback driven from PP2000 the regenerator meter shows 96% load.  With PP3000 it shows 55% load.  Frankly I think this factor might be responsible for most of not all sonic differences that I see between the PP2000 and PP3000. If so then I would like to see the PP5000….

6) Ok, the first half elephant in the room – the dynamics. Believe me or not but PP3000 is more dynamic then PP2000. It was very sensible from the very first note that I heard from the PP3000.  I do not know what to say else about it.

7) The second half elephant in the room – dynamics is that PP3000 looks like provided even further HF attenuation. The upper MF aggressiveness, characteristic for electricity, looks like with PP3000 subdued deeper.  I would say I can run my MF and my tweeters harder with PP3000 to get the same level of comfort. I would say that I can do 1/3dB at MF and one full dB on tweeters. This is very good and it is an indication of PP3000 advantage. IT is very much might be due to the fact the I do not load PP3000 as much as I would do with PP2000 – with the same load but at near full capacity the PP2000 I am sure output more distortions then PP3000 at half capacity.

8) PP3000, probably because more HF attenuation, exposes more texture in sounds.  This is what I did not expected.

9) PP3000 it looks like have slightly “flatter” imaging.  I mead the depth and the complexity of imaging is there but it is a bit more “depth compressed”.  I am still looking in this and will play with it. It might be some fine aspect of grounding or something like this will see. The effect is very mind but I think worth to mention.

The most important in PP3000 in my view is that in PurePower Company did not fuck up with PP2000 sound. It was what I was very much afraid. The PP3000 is just more beefed-up version of PP2000 with more powerful output stags and more cooling.  Still, it might be perfectly possible that despite the PurePower assurance that “it basically the same unit” the glorious sound of PP2000 would not be there. It did not happen. The PP3000 has the very same sound as PP2000 but with differences that I have described above. It is very possible that I would not observe those differences is I was able to load PP2000 with no more than I would say 30% of load. However, a single pair of my Power amps loads PP2000 with 75% and I have no ways to do anything with it.  Since I was not able to make my multiple PP2000 to run simultaneously loaded in the same playback (did not sound right) the PP3000 is the only solution for me.  Not I need to continue harass the PurePower to make that damn bypass remote control and to lobby for 4kW or 5kW version of generator. I wonder what will make PurePower to do it. Do I need to start some kind of movement “Occupy PurePower”? You know, for those audio people it is never enough….

To shunt or not to shunt.
fiogf49gjkf0d
I kind of thinking about it and I am not sure that I have an opinion. In the former PP2000 I stunted buttery with over 100K capacitors, presuming that it will driver DCR of buttery lower and therefore improve the day-to-day decoupling of PP2000 from power lines. It was not instant effect but it did not make anything worse and in a long run it did provide some day-to-day stability. There is no way to say anything certainly as there is no bypass switch. Anyhow, the PP3000 uses 8 batteries instead of 6 batteries of PP2000. This means that it has 2 extra series batteries that for sure raises input impedance of the entire battery pack. Still, the PP3000 sounds better than PP2000. What does it mean?
It might mean:

1) PP3000 used different batteries. Unlikely.
2) The batteries input impedance is irrelevant for decoupling. Unlikely
3) Something else in PP3000 makes the decoupling more effective. Possible.
4) Something else in PP3000 makes the coupling less relevant. Possible.
5) I make my listening during the day when else was not as effective as it might be. Possible.

This all bring back a question:  would it be beneficial to add a large 125V cap across the PP3000 battery? For sure it shall not hurt but would it have any practical benefit? I will hold for now and will live with the unit observing how it react to power in the grid. I presume that it will be beneficial to shunt the battery with caps.

Yes, it is. Now we are getting somewhere! Those “exposition more texture in sounds” turn out to be a bit tricky. I spend 3 hours to experiment with it, thinking about it, make some adjustments, listening and thinking about it again. It is not so simple. The PP3000 did clear up MF deeper then PP2000 did but at the same time it gave some coloration, texture coloration. It is very minor and it is very attractive but it is not what I would like to have. I would like texture to be dictated by source not to be overridden by my playback. This was not regular texture coloration but very insignificant upper MF texture coloration; I do not expect most of the people dealt with it as to moderate it possible only in context of active multi-way. In my experience I saw it only during my tuning of Injection channel when I converted color of Injection channel into texture of MF. So, I recognized that with new cleaner MM I can take my MF out of it “protection mode” and to run is slightly different.  Playing with Injection level, the MF level and the HF level I found a VERY interesting configuration that is in the same time neutral and spectacular. In a way I can get now the immediacy and nuances of MF from my 12F that I was able to get in my old room from 7 feet. It is not more aggressive but rather more presentable.  I was not able to get it in my new home and I was kind of blaming the larger and relatively live room. Well, now it is different.

The MF now are very smart. They are very powerful in term of showing themselves of but they stop posturing exactly where they need to be stopped. Ironically to do it I need 3 MF channels, 3 amps and one PP3000.  I am locking this configuration of my MF channels and my new default.

The small thoughts.
fiogf49gjkf0d
It is interesting that PP3000 effect of the “deeper” MF cleaning is very much reminds the effect of going from an empty room live room to a much better acoustically treated room.

Anyhow, now I would like to talk a bit about stability of the effect. I do not think that the new PP3000 will have any betters power line dappling then PP2000. As I commented I still have some fluctuations of sound quality, the fluctuations minimized by the factor of 200 perhaps by use of regenerator but they still were there. Latterly I begin to attribute the fluctuations to other then electricity reasons but before to do it I would like to make sure that the electricity reasons are addressed.

In the past I implemented large cap bypass of the PP2000 battery that I think gave SOME stability of decupling. The PP3000 has no such additional cap bypass, it has slightly larger internal cap bypass.  Since they, I am sure, went for different type of cap (the voltage is higher) then would it be possible that the quality of that caps made all difference? Another option – would it be possible that they use different type of battery in PP3000. The fact that PP3000 is loaded lightly is very much contributive to better sound quality but I do not think that it was the only reason. I did recognized the different sound between PP2000 loaded at 30% and 90% but it was not the same difference as what I have between the PP3000 and PP2000. Furthermore I made an experiment and loaded PP3000 at 100% load (1.5kW heater+ full playback). The depth of the MF cleaning did not change.  So, what does it mean?

I hate and to happy at the same time to presume that it looks like PurePower did fuck up own generator again only this time they fuck it up in good direction. Despite of this assurance that PP3000 and PP2000 sonically identical, they presumably did something, perhaps unwillingly, with PP3000 that makes it to clean MF much deeper. I do not think that it is topological change but probably some parts that they used turned out to be better for sound or perhaps since they beef it up to get power they use larger parts for higher voltage and that made the sonic difference.  The most important question to me now is: will PP3000 exhibit the same decoupling behavior as the PP2000 had. I do not have an answer. I have PP3000 for 4 days and so far I did not detect any significant changes. Why know what I have in power lines nowadays… again there is no damn bypass switch with PP3000.

There is another subject that makes me wonder. What would happen is I add more batteries to PurePower?  They have now 7A/H but if I make it much larger? For sure the unit will be running longer from batteries – something that I do not care, but will those larger batteries change sound or the decoupling behavior. Larger battery is the same as the cap bypass – lowering inner impedance and it might be much more then this. It is possible that as batteries get older the internal impedance rises and the decoupling get worse. In such case a big ass battery would help. I do not mind to get huge battery but I do not know if PP3000 charger will handle it. A good 100-200A/H battery being discharge will suck in current that most likely melt PP3000. PurePower has one battery packs that they sell for 1000. If they were not so happy and not so expensive to ship then I would try them in order to see if adding more battery change sound or improve decoupling. Well, with very large battery decoupling is not a factor and it possible to drive PP3000 from battery for very long time. I have a neighbor next door with eclectic car, who know, one day he can wake up and it will be a car in his driveway with open hood, remove battery and “Get over it!” note stuck to his dashboard…

Redundant step
fiogf49gjkf0d
Does it not make sense, for the amplifiers at least, to source the power directly from the DC of the PP3000? For how can there be value in recreating the AC, only to rectify it again? Any processing step will add noise, and here that step is redundant....

"HF attenuation" ?

Hi Romy, I am a new user, I write from Italy.

Do you mean that Purepower 3000 "softens" the higher frequencies and the upper midrange?

This would be a good thing for me, I have B&W 803D speakers and sometimes I suffer their "aggressive"/"protagonist" tweeters resulting in a "monitor" signature in their sound. Source and integrated amp are Luxman D06 and l-509u, with very neutral sound (no warmness... "hi-fi - solid state sounding", but even no coldness nor surgical/analytical sound), cables (power, interconnects and two pair of peaker cables in "shotgun" biwire configuration) are Cardas Golden Reference (no extra warmness since I adopted the biwire configuration, which added a "transparency" I did not expect, since the single wire+jumpers solution sounded almost warm and rich in the bass; I liked that sound but jumpers made some other damages so I wanted to remove them; maybe one of the two pairs of speaker cables and the power cords still have to burn-in, I have them since last month the first, half month the latter). 

Do you think that this (1dB?) attenuation of high frequencies results in a stronger bass and cleaner mids ?

I'm going to buy a PP3000 without any possibility of trying it before, and I would like to know how "it sounds".

What you say make me think that PP 3000 is perfect for my system (I upload a photo)...can you confirm that?

There are useful HF and there is garbage.
fiogf49gjkf0d
Biggy,
 
Nope, PP units do not "soften" higher frequencies but rather greatly attenuate them. I do not know how in Italy but in US is a person uses open power lines than I would estimate the 80% of what the person recognize as HF in fact is power lines noise. With this noise removed a lot of “bad” HF is gone. Those removed high frequencies however are not “pregnant HF” but just garbage that shall not be there to begin with.
 
I have absolute no knowledge if PP3000 or any other audio devise might or not might not be ”perfect for your system”. If you need a sales person why would butter you with subliminal messages and promise assured place in have is you but this or that devise then I would suggest you to find another forum to ask those questions.  I do not provide any consulting about purchasing decision and I very much do not give shit what you or any other person buy. I hope my brisk attitude eliminate any follow us questions of that sort.

Maybe I did not write well what I mean, I was not asking you "if PP3000 is the right choice for my system", but if you can confirm that it attenuates the higher frequencies (since that's what I need).

My B&W speakers are very (maybe too much) "revealing", and I often feel "too much bad HF" (maybe caused by the bad electricity).

If you can confirm that PP3000 elimitates all bad HF resulting in "attenuated HF", the consequence is that PP3000 is perfect for my system.

Hope I've better explained what I mean this time.

Trust me, I do not worry.
fiogf49gjkf0d
It is not necessarily so. You do not complain about HF harshness due to electricity problem. You complain only about excessive higher frequencies. However, the excessive higher frequencies might come from zillion another reasons, including the topology of your loudspeakers. So, why do you feel that anybody in right mind would advise you to deal with electricity of it is not know if electricity is you problem to deign with? I understand that you apparently do not have experience with influence of electricity to sound, as it you were then you formulate you question very differently. Also, if you were then you would be able to distinct between excessive higher frequencies die to bad electricity and the excessive higher frequencies due to other multiple reasons. So, I did not hear your playback and have no faith in what you identify as problem of you playback. So, naturally I have nether interest or desire to extend any recommendations.

You would be a fool of you pay $5K juts because you read at this site that PP units do HF attenuation. You can attenuate HF by running a layer of toilet paper around your tweeters. Do your home work, educate yourself with what your actual problems are and then, if you want ask intelligent questions, not the bogus one.

Very unkind ...
fiogf49gjkf0d
You force me to say that you are really rude person , or at least you make an effort to be so .

Do you really think I'm so stupid to want a line filter which costs $ 5000 only "to reduce high frequencies " ?

The electrical line in my houseis terrible(all outlets connected to each other, the last one giving power to my audio system), the dishwasher or washing machine or dryer or vacuum cleaner or oven are always running; for this reason often blackouts occur, with possible damage.

When in summer I switch on the air conditioner I hear a "click" from the speakers; when someone activates the the elevator I hear an annoying hiss in the left channel.

I listen with pleasure usually after 11p.m. ; in the morning system is more "harsh" than in the night.

FOR THESE REASONS I believe that the "excess of high frequencies" may be due to poor electricity, and that thePurePower3000, according to what YOU said ("it reduces the high frequencies of 1dB") I thought it might be a possible final solution to my problems (even aware that the excess of high frequencies could be due to 1000 things,:the type of speakers, not all the cables broken in, early reflections in the listening room, etc..)

Maybe I will do my home work and educate myself with my problems, but if you continue todo "the master" this way, without educating yourself to understand how to live in peace and armony with other people, I think you'll continue to post on your forum alone.

Goodbye

Do you really think I'm so stupid to want a line filter which costs $ 5000 only "to reduce high frequencies " ?

The electrical line in my houseis terrible(all outlets connected to each other, the last one giving power to my audio system), the dishwasher or washing machine or dryer or vacuum cleaner or oven are always running; for this reason often blackouts occur, with possible damage.

When in summer I switch on the air conditioner I hear a "click" from the speakers; when someone activates the the elevator I hear an annoying hiss in the left channel.

I listen with pleasure usually after 11p.m. ; in the morning system is more "harsh" than in the night.

FOR THESE REASONS I believe that the "excess of high frequencies" may be due to poor electricity, and that thePurePower3000, according to what YOU said ("it reduces the high frequencies of 1dB") I thought it might be a possible final solution to my problems (even aware that the excess of high frequencies could be due to 1000 things,:the type of speakers, not all the cables broken in, early reflections in the listening room, etc..)

Maybe I will do my home work and educate myself with my problems, but if you continue todo "the master" this way, without educating yourself to understand how to live in peace and armony with other people, I think you'll continue to post on your forum alone.
If you were a bit more observant then you realized that I quite intentionally drive from my site whoever I have no interest in. I am not your sales person and I have no intention of interest to butter you up with promises and assurances that a new tow will address all your frustrations, all your frustrations. I know, the audio people are accustomed that somebody take them by the throat and dump them into a cesspool of the “equipment of the month”. I have no personal interest to do it. I do not give shit what you buy and what problems with your playback are and how will you address them.

If you form a question or express a frustration that would indicate some thought processes (BTW, something that you were trying to do in your last post) then I do replay and I usually quote helpful, or at least am trying to be. You come to this site with the picture of your leg and ask question “Who shall I merry?” to me it is an idiotic question and I am not willing to waste my time entertain you. Find another site where people will be more polite, compassionate and will be happy to wax poetry about each of your cable elevator. THAT type of “harmony with other people” is something that I do not have interest within neither my site nor in my life.  You need to do a home work not only about “bright sound from playback” but also about “what to expect from others if I do not know what I am looking”.

Free audio psychiatrist
fiogf49gjkf0d
Romy,

 An interesting (and somewhat scary) poster. You are minding your own business  and going to the trouble of setting up and maintaining a vast website on all kinds of audio issues. So someone from Italy shows up and expects you to be his audio psychiatrist for free. Someone who obviously assembled his audio system based on people pretending to be his audio psychiatrist but making him pay for the privilege by sticking him with whatever they were selling. Then he gets huffy when you decline and spits out issues on the face of it requiring his own power plant and I mean the big utility kind. Then he angrily complains about you disturbing world harmony with your attitude. What's interesting is that he doesn't get that the Italian electrical utilities are run by people expecting a free electricity psychiatrist to help them. What's scary is that all these people are going to demand the creation of Harmony Police who will enforce their demands for free (fill in the blank) psychiatrists.

What to recognize is true HF

 Understanding what is different and pose those things into your questions. Without indicating what your change in sound is after 11:00pm it is difficult to suggest how the regenerator might help. I think what you recognize as HF troubles is what is to be self evaluated. 

 Speaking of the Purepower 2000 I will say in my experience that those differences of day and night listening go away (well almost). Among many other things it is not a HF attenuation as you suggest. There are many other ways to attenuate HF. It is more a seperation of musical signal from outside effects. If you read this thread thoroughly it might help you recognize this. It looks to be new ground for you as it once was for me and all of us at one point.

Emanueleeeeeee....

Steverino,

I do not have anything against Emanuele. He does what he does or more accurately: what the industry idiots taught him to do. In business, anybody product address somebody frustration. Then industry idiots made the generations of the audio people do not deal with the actual reasons of frustration but rather they built in audio people that stupid desire to buy a new audio product as a  proposed “remedy” of frustrations. It is like pharmaceutical companies: they do not promote healthy life style and do not fight government against poisoning pubic; they instead develop drugs to cure symptoms. Emanuele is just a victim in this well-oiled mechanism. For sure Emanuele is right about my rudeness but I very much proud about it. I feel much more RESPECT TO THE SUBJECT under discussion when I refuse to be involved in brainless conversations.  Where is that idiot, the PurePower sales reps from Florida when we need him? If he was around then would not only “take care” of Emanuele, but pat his hear, clean his nose and perhaps even wash his underwear…

PP2000 not a panacea
fiogf49gjkf0d
Hi Emanuele,

FWIW, I've been disappointed with my PP2000 (the 230V model). I love the sound then it's running from battery, but think it totally destroys the sound when running under 'regenerator' mode. And as Romy has pointed out, this is totally unacceptable. Unlike Romy, I'm not prepared to return my unit to 'have it fixed'.

HTH.

Mani.
