Something Odd...
fiogf49gjkf0d
Yes, Romy, it is certainly an info-mercial first, with all the usual flash/buzz "facts" in play.  Also, although all "studios" I know of are "balanced", many of the "hot-rod" studio guys also use all sorts of "power conditioneers".  For one thing, it is not a given that a piece of equipment will run properly off balanced power.  For another thing, if they are using balanced power in the first place, then why do they need the power conditioners?

The thing I found most interesting in the piece was the explanation about contamination of the neutral/ground wire by the gear that's on the line.  Although this gibes with my own experience, it hardly addresses those rare days when the electricity is good and I simply get a free pass on all the theoretical BS, like none of it is happening at that time, or who cares if it is, since it doesn't hurt the sound at the time.

Best regards,
Paul S

A new PurePower 3000+
fiogf49gjkf0d

The PurePower folks visited recently a couple of my local audio guys and brought with them the new units. With all my admiration of their products, I was kind of if not skeptical but caution.  I told to Bill that if he tried the new PurePower 3000+ unit and if they do not blow then he needs to let me know. Furthermore, we had an agreement that if he feels that if it worth listening the new PurePower 3000+ next to my PurePower 3000 then he would let me know. Bill called and told me that I definitely need to hear the new unit…. to my pleasure and in a way to my disappointment.  Pleasure is to know that allegedly the new units do sound interesting compare to the older units. Disappointment is that now I need to go over the pain to evaluate the new units and to get some bottom of PurePower+ sound.

Well, to make the long story short I have in my listening room a lender of the brand new PurePower 3000+ and I am looking at it for 2 days, not pluging it in. I sent Amy tonight to play her quartets and was planning to give to the new PurePower 3000+ some listening but then deseeded to spend some quietly time with myself, not harassing my ears with audio frustrations.  So, it is an evening of tranquility with no concerns of electricity…

I met PurePower’s Richard and his wife. He did some listening in my room but we did not pay with their new units. Richard told about the company, history, the problems they had, plans, straggles, how they dealt with all many issues that a typical for small scale high-end manufacture. They are foe sure in tough business. PurePower is not Magico. They are not rich industrial investors who just found out that they now can cash on “making audio”. They are pretty much a family business who does it fully-wasted, considering the industry and considering the complexity of this product I would not like to be in their shoes…

Richard did not strike me as somebody who was looking for any advanced musical or audio interests. He was rather practical, business-oriented person, which is perfectly fine. He did demonstrated quite high confidence in his new unit, which was very nice to see.

There was a very interesting conversation. I persisted that PurePower pretty much accidently has that wonderful sound and I had a concern if the new unit might not have it.  Richard insisted that they have a very precise and very accurate vision what in power regenerator make it to sound right. He stressed that the new unit is not only the Chinese version made in Canada, incased into two chassis with a few minor semi-cosmetic improvements but the further advancement of PurePower’s vision. He state that they played with a few key operational parameter and they feel that what they have achieved crates a condition for much better sound. The statement of cause is very loaded and at this point I have no idea if it relates to any reality.

I have today a day off and I think I will be playing with the new PurePower+. I am a bit skeptical as I have no specific power frustration as now and the playback sound spectacular (after my stupid last night “fix”:  http://www.GoodSoundClub.com/TreeItem.aspx?PostID=19438). The most encouraging to me feature of the new PurePower+ unit that it has bypass switch, wish is economically feasible to have as I run my SS units all time and I would like to leave it on in bypass mode, activating the regeneration only when I am listening. I was begging PurePower for this feature for years and now they do have it.

Never Received my PP3000+
fiogf49gjkf0d
Gosh,A personal visit from Richard! I'd love to hear more, Romy. Richard has sent me so many e-mails promising to send me my PP3000+ replacement unit from the next batch of units he makes, but of course he says that every time, and has been doing so for what is now literally years. I would love to also be able to report back on the sound of the new and improved PP3000+, except that I have never received it.Adrian

Adrian, as you understand I am not in position to talk on behave of Pure Power and I do not know your situation. However, as many other thing with Pure Power - it is about waiting. From what I understood since they move the production to Canada never were able to keep the production up to demand and they were working to make the in-house production more technological. I think it is new field for them and it took some time to develop necessary capacity to do it. I perfectly can relate to it.  Reportedly they recently did get those methodologyes and staring from this summer they supposedly will be able to produce the PP3000+ way more sufficiently. As a result, as they have more units in their hands, I presume they will be able to address their replacement debts with you. I think that all might be very much true as why would Richard otherwise go out of his closet now? I presume that Pure Power’s visit of their dealers, reviewers and me in New England is a sign they begin to feel very comfortable about themselves, which is very nice to all of us.

You will be surprised but I did not try the PP3000+. IT is sitting in my room for 3 days unpacked. Amy, have asked me why I am so strange about it and why I do not try it. This is an odd feeling but I keep postpone it. I think this end of the week will be very much the PP3000+ week.

Slow replacements
fiogf49gjkf0d
Hi Adrian,
We look forward to your receipt of a shiny new PurePower+ 3000 as much as you do. You are one of about a dozen customers who had our previous 2nd generation units in need of repair under warranty.
We had, for obvious reasons,  severed our relationship with the Taiwan outfit to whom we had outsourced our production, so we exhausted our supply of certain replacement parts and were able to offer a  repair only service. To fulfill our responsibilities to our customers, we offered to replace any faulty or unrepairable in-warranty old model with a brand new PurePower+ equivalent. We were certain this could be accomplished in a timely manner, but as it turns out it could not. 
The amount of hand building in the new 3rd generation models resulted in a production speed that left us unable to produce enough PurePower+ product to both meet our minimum delivery requirements and supply timely warranty replacements.
We tried to keep all affected customers advised of our progress and to reassure them that we were determined to make good on the loss of enjoyment of their PurePower regenerators - but a year is a long time to keep their faith alive. 
We understand their impatience, and we share their frustration. If we had been able to increase production to supply all outstanding back orders more quickly we would have done so. The demand for PurePower+ products has been more than double our ability to deliver.
There is good news to report.
We have just begun production with vastly streamlined assembly methods and will be able to meet any expected demand. Adrian will receive a brand new PurePower+ 3000 by the end of June. We expect it will take until late July to fulfill all remaining service replacements, but Adrian is near the top of the FIFO ordered list.

Balanced Power
fiogf49gjkf0d
I have two balanced 240V/120V Equitech 3kVA step down transformers at the head of my system feeding my two breaker boxes.

I have emailed PurePower several times over the last year asking if their units can accept 120V balanced power (+60V/-60V). I always received a prompt reply that they would check into it and get back to me. Unfortunately they never have.

As PurePower seems to be back in the market perhaps they could make a definitive reply as to whether their units accept balanced power. If yes perhaps also they could comment as to whether there would be any advantage to supplying balanced power to their units.

Thank you.
George

What Problems Do You Hope To Solve?
fiogf49gjkf0d
George, since you have been using the Equi=Tech units for a while now, what do you like about them, and will you compare the sound you get with and without them?  Also, what do you not like about electricity with the Equi=Tech units in place, that you hope the PP will improve on?

Best regards,

Balanced input for regenerated power.
fiogf49gjkf0d
Hi George,We did find an email response from Damian to you in early 2010, suggesting that we could think of no technical reason that a PurePower unit would have a problem with +/- 60 volt input. We routinely operate our 230 volt models with two phase +/- 120 volt input.

So you do not know if it will work or not. I see now why I have not bought a PurePower.

Hello Paul,

I find these type of questions very difficult to answer. I bought my first Equi=Techs in 1995, not too long after they introduced them to the audiophile community. I do not think there were too many other options at the time. I replaced my old units in 2001 when I moved. As we were doing remodeling it gave me the opportunity to listen with and without the Equi=Techs. Dedicated lines made a big difference and the Equi=Techs added a certain refinement. Really I think all you can do is listen with and without and make your decision. The next guy may make the opposite choice. In 5 years you may make the opposite choice. I am actually curious what my system today would sound like without Equi=Techs but given how integrated they are into the system it is not worth the trouble for me to bypass them.

I also run a parallel H/T system. I have replaced seven switching PSUs with linear PSU's (the only switching PSUs that remain in the system is projector and sat receiver which I am working on). To me the audio improvement was significant. Other listeners don't know what I am going on about, ie, what I heard was unimportant to them.

Today there are many balanced transformers available other than Equi=Tech. I have read you can pick up used medical grade transformers very cheaply. Perhaps you could pick up one of these and see what effect it has on your system to your ears.

My PP2000 does NOT like a balanced input

That's interesting. I use a couple of 5KVA balanced transformers. I tried to feed my 240V PP2000 with one of them, but the output was non-symmetrical. It seemed to me that only the +120 volt phase was being regenerated.Mani.

UK balanced power
fiogf49gjkf0d
Hi Mani
The UK  240 volt utility system  does not parallel the North American 120 volt system - and is also quite different from the North American 240 volt scheme used for household stoves and dryers that uses split phase 120 volt legs to present a 240 volt supply. In our plant, we have both a 208 volt supply generated by 2 120 volt phases of a three phase supply to power our nominal 230 volt international units as well as a step up transfomer setup converting our 120 volt supply to 220, 230, or 240 as desired. So it is a matter of apples, oranges and tangerines.
To answer Georges question, we did not buy a balanced power product in order to lab test his situation. We can't see the utility of using both products. If using a balanced transformer to cancel noise resolved his local utility power issues then we are pleased for him. If he wants to find out if PurePower regeneration offers an even better result by providing unrestricted current and accurate guaranteed voltage, he should take the opportunity to try our product. He can plug it in to the wall outlet and listen. If he wishes to experiment he can plug it into the balanced power output, by all means. Should that provide double the pleasure he could make 2 companies happy at the same time.

The Pure Power 3000+, the day one.
fiogf49gjkf0d

After 4 days of suiting in boxes in my listening room today is my day off and I decided to dedicate it to play with the new Pure Power 3000+.

PP3000+.JPG

I desired to use just records and connected all amps, preamps and phonostage to old unit, disconnecting everything else. I relisted the first movement of the Tch 6, Mravinsky 1961, I know that recording very well, and even it is not the best “audio quality” it has in there all the I need to hear and even more.

Switching 5 cables to PP3000+ was no brainer.  The unit shows 50% load.  All power cables are lifted ground (in old and new units). Bothe of the PP3000 and PP3000+ are plugged into the same dedicated power line, phase A.

No, contrary to the comment I nears I have no noise from speakers of any kind, in fact it was no difference at all from noise perspective. Just for fun I measured the AC nose on the filaments of my DHT of the Milq mid channel. The folks who played with direct heated triodes know that this place is the most sensitive. I have 0.7mV with old unit and I had the very same with new. I maxed out the phonostage at its full 84dB gain. No noise of any kind, the same as with old unit. So far so good, the folks who reported that PP3000+ had “noise via loudspeakers” need to find out how to address own ground loops.

The initial sonic result is auditable instantly at the very first bar – a large portion of HF extension is not there anymore. The the glitz and confusion at HF is removed. With older unit the lower bass is slightly softer and defused, the sense of rhythm is slightly less pronounced, the first violins slightly earlier chock my own recording crescendos, the woodwinds re more lay back, more creamy, with no whistling intend. There is nothing else to say – it is as simple as that.

It is not about the proverbial HF noise however, it is more about the new definition of beat that the new unit has. The new unit injects some very definitive sense of rhythm. I can’t compare it to anything else then to bring an audio association. If you try to compare the CEC TL0 transport again peaty much anything else out there then you know what I mean. The TL0 reads very hard with spectacular rhythmical articulation.  The same rhythmical articulation the new PP3000+ feels like showing only the PP take it further: it feels like it throws some kind laser-distinctive rhythmical differences.  This new super pace is not about rapidity of sound but rather singularly of sound that is not necessary pleasurable thing. I did switched back to the old unit a few times and to a degree I do see the merits of using the old unit legato-like rhythm.  I need to listen a bit more and to get use to this super articulation of the new PP+.  Does this super verbalization make sense musically?  I do not know year, this is attractive and might be even addictive but I need to think about it. For whatever it worth the new PP3000+ looks like a new unit with very different performing capacity.  The PurePower people told me that this is basically the old unit that took many of the old unit ideas further. That might be the case but for sure this is the example where the quantitative approach did give birth to a new definition of quality. Now I need to think how this new quality might be used in context of my playback. At this point I do feel that this new super articulation has in a way always mechanical nature and I am a bit cautious about it. I need to think more about the way to use this new opportunity.

I did not measure anything, did not test bypass, buttery operation or anything else. As the initial exposure I would say the result did exceed my expectations and was well worth it. It is certainly a very new sound from Pure Power and if they learn how to make their units stable and reliable then they could stand up very arrogantly and the product they have is very unique.  The best thing so far that Pure Power took his old wonderfully sounding unit and converted it to a new generation of Pure Power sound. Considering my firm believe that they have no idea what they do (neither anybody else BTW) I was very afraid that they would kill the accidently-wonderful sound of the old PP3000. They did not do furthermore then took it to very right direction. That is very pleasant to see.  It is possible that what Pure Power does has already nothing to do with electricity itself but rather it possible that they got a grip how to pre-condition power before PS in order to make it to sound more interesting.  One way or another but I feel it is very stimulating direction to go.

Hmmmm
fiogf49gjkf0d
The post sounds like the 500 word synonym for "analytical". In my experience most changes from a satisfactory prior model means it gets more analytical rather than more like live music. Your description is very close to what I would have written about the Audience power filters. They do work fine in an AV system however. Hope this changes upon further break in.

I will reserve judgment until I receive the unit. I hope I actually get it. I think since Romy has got his, maybe there is hope. If I ever get the PP3000, I will certainly report that here and post a review of the sound of the unit as well.Adrian

Hm, interesting….
fiogf49gjkf0d
I would not use the word analytical but rather mechanical. Analytical, at least to me implies sorter degree of investigative anal retentiveness and I do not feel that what is going on with my current PP3000 sound. Whatever it is does not hurt my felling of musicality and does not take my attention away from performing intend. It is rather a bit too mechanical by texture and slightly over-antisepses the ingredients of sounds instead of depicting the sound as whole. Think about you making a pasta salad with 15 ingredients and you slightly undercook all of them. So, eating the salad you get that distinct feeling of individual elements that do mix into the whole ensemble of taste but they distinctly say to you what is what. It is not so bad in music but it would need in my view a bit more gestalt-like behavior. Saying it I think that to a degree it is an interesting environment to experiment with sound in THAT framework as I do see some benefits of it as well, I juts need to look into it more. I truly would like to be able to use the bypass mode as  it might refers to the sound of electricity we have today in power lines. We do have during the last 2 week a very good electricity and I need to be able to observe the performance of PP3000+ in context of the quality of electricity we have in the mains. the burning-in might be a beneficial thing of cause…

Is the Bloom Still on the Rose?

Sometimes when the harmonic bloom is diminished, especially upper bass and lower MF, I would describe the sound much as I hear from you now.  I have 20 minutes at the most worth of patience for this, then I am out of my seat.

Mechanical no more
fiogf49gjkf0d
This morning I sent the wifey to work and sat listening my music. As I played the first track it was absolutely self-evident to me that the mechanical isolation of sounds that I reported yesterday was no longer there. Even the unit was ruining all nigh I really do not buy the break in theory as it was too much. It is not that I neglect break in but the difference too much to be believable.

I desisted to two more the old unit and straight wall sound and then I realized that the Mechanical sound from the new PP3000+ has returned. So, eventually I recognizes that the mechanical sound from the new unit come from the fact that I have old unit sitting unload in regeneration mode right next to the new PP3000+. I have reported that I was not able to make more than one older PP3000 to work together in my system as they sound too bright. The new PP3000+ apparently has the same behavior only instead sounding too bright it sound mechanical when it near old regenerators. Interestingly that it feels that the old units do not sound bad if the new units are at proximity.  So, to get better sound I need to shot down the old regenerator completely and then I have no mechanical feeling from new regenerator.

Hm, something is wrong.
fiogf49gjkf0d
Hm….. I am not sure what is going on.  Decided to plug the whole playback to the wall and to hear how it would sound.  As I did it felt kind of lost. It sounded spectacular, in fact if sound as wonderful as the new PP3000+ regenerator.  Does the new PP3000+ is as transparent as doing all double conversion it has virtually no impact to the sound of electricity. Honestly I am doubt but with all my desire to recognize the difference in sound between the PP3000+ and wall sound I do not see too much difference. I think with new regenerator it has very slightly more dynamic accent but to such low degree that I am not sure that I am not hallucinating. Hm, do I need to wait when electricity in the wall turn worse then to see the PP3000+ contribution more distinctly (we have very good electricity last 2 weeks)?

I think we are back again to the issue of the dedicated AC lines and what external (outside of the home) garbage can enter through them. My own anecdotal impression is that there are two opposing trends from the power company. One is positive in that they are replacing old equipment. On the negative side increasing digital monitoring devices are throwing more nasty garbage into the powerline. (A good question is how far such noise can travel from the source.) I think Romy when he was measuring such things a year or two ago encountered bursts of extreme powerline noise. But then they would suddenly disappear. Since the dedicated line minimizes within home pollution it should be ok in the good days. I have seen comments at other sites where people moving to the dedicated line felt that solved their problem and they didn't need the AC regenerators. For myself, I would say my (old version) PP unit mostly evens out daytime and nightime audio system performance rather than making some more fundamental change. It's probably more essential in countries which have Very unreliable power grids.
