Wojtek, there are idiots out there and they run across web sites, skim the pictures and run to buy the things, considering that if I or somebody else use something then it is an automatic “recommendation”. I have a long list of sites where people are bitching about me and call me horrible names (I get them from References of my web log) juts because they seen that that I used something and they presume that they much have it as well. In fact I had an idea to publish all of those “feedbacks” but to ridicule pure idiots is too boring. Just two week back an idiot with name Franz went to “My playback” section looked that I use Dominus cables and bought a large party of POD cable. They sound like shit and the pissed guy posted a large article describing how ignorant I am and that any of my recommendation much be discarded. You see the idiot did not even invested efforts to read my comments about POD cables but was motivated only just by images on my site and the believe that I use POD cables. Yes, from one perspective I might be proud that I have such a good reputation but this pride has a “minor” blemish: this reputation exist ONLY among idiots, which is unfortunately a majority in high-end audio

The truth is that any sane person in high-end audio do not give shit neither about me not about anybody else, very much how I do not give dams about others. We all practice audio explicitly for ourselves, period. All collaborations and all experience of others are important ONLY for informative purpose. I went to such a great extend with PP1050 and later with PP2000, I kept my entire history with PP public and I feel it had and has a great informative purpose. You will not find anywhere more information about PP. Does it help to sell the PP generators?  Do you think I care? I can say that the events of this thread did reportedly broke quite a few sales opportunities for PP. I identically do not care.

Wojtek, in your life, will anything change if PurePower, Lamm of Ortofon will ship next month and few extra boxes. If you do not think so then why do you feel it would affect anything in my life? Yes, the people do run across this and other web sites and search for “what next to buy”. This is one of the reasons why I feel that audio people are Morons - they are not trained by stupid reverse to use “information” but they only search their brainless dally dosages of audio imperatives. Sorry, if I work with animals then I would prefer to herd Cats, not the stupid sheep. You can’t milk them but you feel better around them….

Romy:you must mean person with Zu Druid. What did he not like about Druid in the end (bass aside)? What did he not like about Altec? What off-the-shelf speaker is he going to try next, or will he throw it all in and stick with Bose table radio? Or Dunlavy??I am not saying there is no problem with Druid or Altec. I am sure there are many. I am wondering what was particular about his reasons for abandoning them both?

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.)

Ok, I got my two more PP2000, not I have 3 all together and I need to find how to use them. My little celebratory mood with PP2000 is much shorn live and my old PP2000 flying back today to Canada for fixing the problem with the “fuzziness”. The PurePower folks promised to do it fast so, she will be back… I did not measure the new PP2000 yet, in fact I did not run the system from 3 PP2000 yet – I did not have time to amuse myself with audio last night. What however, I had last night was a sort of disappointment that I do not know how to rectify at this point. The PP2000 use that I use almost for 2 years was one of the first new PP2000 that PurePower produced. It is not too noisy but it has indicated own presence in a room. So, planning for two more units to drive my two 6-ch Melquiadeses I thought to place the a pair of PP2000 in the basement directly under the PP2000 Melquiadeses.  To do so I made holes in the floor for power cables and accommodated the stands for PP2000 under the floor. I have my electrician to run dedicated 20A lines to the future locations of the  PP2000  in the basement. Furthermore I stressed PurePower to make a remote control turn on/off options on my units, presuming to turn the Melquiadeses by remote turning on the regenerators – each Melquiades will be plugged in own PP2000. So, I thought and planed for everything but I got screwed in a way. The two new PP2000s that arrived turned out to be practically silent in operation. Whatever noise then make they are even comparable in noise with my two years old PP2000. Looking at this silent operation I ask myself why I need to put them in the basement - the can perfectly sit in my room next to the power amps. So, now, presuming that my current old PP2000 will be upgraded to the silent status I need to revise where I would like my regenerators to stay, revising the location of the holes in the floor and the location of my dedicated 20A lines. The new silent operation of PP2000 is certainly not a bad thing but it does screw up my plans how I thought to use them.

Since I installed the 3 of PP2000 units they do work wonderfully. Since my days 2-3 years back when a turn of power switch on PP1500 required to dress in bomb-squad outfit and when any switching might be the very last switching, I kind of have the Pavlovian Reflex rear to tune the PurePower On and Off.  My PP2000 is working flawlessly in my how foe 2 years but I hardly ever turned it on and off. I was so fearful to turn it on or off and what I moved to my new place I was considering do not turn it off and let it run from buttery.

Since I got the 3 units, I still keep one running all times – for front end, DAW and so on, but the two other PP2000 that driver Milqs I tune on and off all time – and the do perfectly fine. The PurePower Richard told that this is normal way to operate the PP2000. I still did not go over my Pavlovian fear but I have to report that I experience no problems now.

Me old PP2000 with the fuzziness problem was upgraded to the latest version PP2000. It turned out that I need to pay for this, whish sucks but I think it was worth it. So, I ended up with 3 newest PP2000, 2 of them with remote control.

Somewhere above I noted that I felt that the new PP2000 a bit brighter than the old one and a bit less protective to AC lines then the old PP2000 was. I reported it as I detected some fluctuation in sound quality during a day and between the days. Eventually I have discovered what caused it, fixed it and it was NOT due to the PP2000 operation. So, the PP2000 is exonerated from my earlier suspicions. 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 less then it was before.

There is another cool discovery. I installed external stand-by generator. It is suburb and light goes off sometimes (it was 3-4 times since I moved in). So, a automated, self-starting, naturals gas powers 7kW stand-by generator would give some piece of mind with heating system, water system, drainage system, PC servers etc…. There is an interesting moment in it however. The stand-by generator (by Generac) produces between 62Hz and 63Hz. My APC UPS machines that power my dev boxes and servers do not read anything above 62.5Hz. As soon my generator rise above 62.5Hz the PLL stop truck it and the UPS flip to battery operation. It looks like PP2000 doe read the odd frequency, this is good news. What I would like to learn if the PP2000 sound as good what it driven my stand-by generator. The generator outs VERY ugly wave, it is not even wave but a pure crap. The PP2000 shall kill it to DC anyhow but in practice the input super ugly AC shall affect sound. I wonder how much affective it would be….

Anyhow, the 3 of PP2000 are ruining and I do not have to say anything about them. They do what they meant to do; they sound fine and then do not malfunction. Probably the whole thread about the evil electricity might be coming to it’s logical end…

This is of great interest to me. I'm having a dedicated mains circuit installed and was wondering whether the PP2000 would simply corrupt the line that feeds it. Romy, any idea how best to measure such 'dirt' going back into the line?

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?

My initial idea was to run just sensitive digital equipment and the preamp from the PP2000. But actually, there is no reason why I couldn't run everything (except the PC) from it.

I went over the very same stages of being cautious. To run the “sensitive digital equipment”, different isolation models, “everything except PC”. Then I plugged everything in this damn PP2000….

At the moment, I run the PC on the utility line, through an isolation transformer. I'm concerned that by doing this, I'm introducing ground loops into the system. I say this because using the 'ground loop isolators' that are supplied with the Model Two seems to clean the sound up quite significantly. I haven't tried running the PC from the PP2000 output, but feel that I'd be defeating the object if I did. Of course, one solution might be to use a laptop on battery power...

I do not know, Model Two was not supplied with 'ground loop isolators', so I am not sure what you are talking about.

manisandher wrote:

Romy, how do you power your DAW?

There is one more consideration that was more important that ground considerations what I moved my PC under protection of PP2000. It was the protection of “neutral”. You see, we have neutral ground and hot. Neutral is theoretically grounded in main distribution panel of your house but the 100s of lines that lead to this panel are usually confused. Some of them use neutral as ground and ground as neutral. So, 150 feet away in your house you have some potential between ground as neutral, what kind potential – it is depends how many fuck-up connected devises you have currently have in your house, street, block, town on and how good their input transformers are. As you understand it is imposable to control it. However, the PP2000 generating a new wave not truly crate for you a new “neutral” but as I can see minimums the neutral to ground variations as it make mostly my own equipment to affect the neutral to ground stray voltage. It is only if the PurePower did not fuck up and do not make tier units to have 40V-50V between neutral to ground as they did in the past.  BTW, I did not measured how much they have now, I shell do it.

Now, the reasonable question to ask: how my DAW sounds from PP2000? I wish I know the answers. I wish I would tell you that I spent weeks to connecting my DAW to different sources and try them. I did not do it. I have connected DAW to PP2000 one day and I did not feel that it made worse sound – which was all that I was hoping for. I can’t give you more details.

The only experiments that I was able to do is to run PP2000 from buttery and compare it to what PP2000 does what it runs from AC. This time it was very sorry unfortunate test. As soon I shot down at all 3 PP2000 AC input and the PP2000 switch to own battery I immediately got my bass back. It was so obvious and so apparent that it count not be even second thought what was the problem. I was listed a few opening bars of Tchaikovsky’s Second Movement of the 5th symphony (guess by who?). The opining cellos and basses has a lot of texture, transients and “strings bite” when playback runs from PP2000 buttery. As soon the PP2000 is switched to run from AC all bass colors are gone, the values of transients are filled with gray noise and the distinctions between the bass notes are virtually gone, Sound become boring like hell…

So, something is certainly is very wrong.  The very first PP1500 unit that I got 3 years back had absolutely no difference in sound between running from butteries and running from AC. My unit #7 that was very nicely working in my home foe over a year had very minor between butteries and AC, practically negligible difference. Those 3 new units had huge between butteries and AC. I am afraid that PurePower peoples loaded capacious into the units to suppress the HF residual spikes that they had from buttery charger and accidently they killed the Sound of the things. I mention it because you will have the absolutely the same effect if you add capacitors to the primary of your PS transformer – shunting caps on AC lines kill bass…

Anyhow, I am not convinces that it is the PP2000 fault – I have 3 units and I need to make the same test running everything from one units as 3 units give some ambiguity. However, there are very strong evidences that the last PP2000 has issuers. I might not detect it when my AC will be in better shape but today ether my AC or the PP2000 running not from butteries are truly horrible. It is sad as I did not sign for THAT.
