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…
