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 ...

Well, I think the short answer is yes.What the people over at Technical Support have told me is that this is due to the power supply design of the amplifiers that are being driven by the PP2000 and that it seems to be characteristic of certain types ...

I ordered a unit at the end of December and was told it would be shipped in approx. one week. However they ran out of units and the delivery time will probably be the first week of February. I'm tying to maintain the patience of Romy. The only thin...

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 ...

[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” ...

Debating the everlasting Leo Tolstoy’s question “How Much Land Does a Man Need?” I wondering how many and what kind PP I would need. I am debating options: to get two more PP200 or one more PP3000. I wonder if anyone used two separate PP200 for rig...

[quote user="manisandher"] 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 int...

If I bought a case of a good wine and loved it and so then bought 3 cases of the next vintage because I was assured it was better year and the wine arrived and I tasted the wine and it was horrible I'd be upset also.

[quote user="Romy the Cat"] Furthermore today to insult the injury it look like my theory about the PP2000 “transparency” to input noise blew in my face as today the wall electricity sounded much better than the from PP2000, that is what I did – disc...

This morning I was listening Messiaen’s Tarantella-Symphony powering system from the bare AC lines. It was far from the sound I would like to have and I decided one more time to insult myself with PP2000. This time I decided to take another PP2000 un...

[quote user="oxric"] Romy:
You may in the meantime build your own battery pack to increase the playtime you get from batteries. When I last spoke to PurePower (I placed an order for a PP2000 in another life and then cancelled the order), I ask...

Yesterday I spoke with PurePower folks and they are looking into what might be the problem. They do have a log of all changes were made and I hope we will be able to find which one did the damage. There was however very interesting development. Last...

I would like to shade light about what is doing on with PurePower PP2000. I know that the readers of my site have own brain, at least some of them, and they do not need me or anybody else to “shade light” on anything. Still, since I was the initi...

[quote user="AOK_Farmer"] I am ready for a subwoofer sized battery pack by the house electrical service feeding the audio dedicated lines. Whats wrong with this solution? It doesn't exist yet? Heck, $15k in the grand scheme of things...[/quote] Steve...

I don't have a scope, so can't measure the output of my particular unit. However, if I were to guess, I would say that my unit probably falls alongside your #2 unit. When run from AC, the bass disappears and the sound becomes bright and edgy, to the ...

Have been intently watching this discussion while on vacation. Returned last night and turned on system and one of my three units was given off a very low intensity buzz into the speakers. Detached the power cord and it went away and on replacing th...

Well i've been using this fine piece of equipment now for nearly 2 years with total satisfaction. My class D Nuforce SE V3 amps love the clean clear power. As i use my PP2000 for my whole system so does all other components in the audio chain. For th...

I've now been using three of the PP2000 now for 6 months and in that time There have been no further hiccups since one of the fuses went out. They are giving me the best musical enjoyment I've had from my system in 30 years of trying to cure my elect...

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...

Clark: You heard what units can do in my place.Romy: Took your advice and added high frequency rolloff to the woofers. The sound did clean up the way you predicted. Now if I can get my subwoofer amplifier back asnd rebalance the system.Paul: Am erxtr...

One opf my amps buzzed when connected to the Pure Power but it was due to the fact that the manufacturer forgot to laquer the lams on an inductor.Have run bot my and Romy's units up to 100%, and even shut down Romy's unit overdriving it with as Crown...

Paul,I finally received my unit in February 2010. After installing it there was an immediate improvement to the sound of my system. I live in an apartment near downtown Boston. My playback varied from day to day. It proved to be very frustrating ...

"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...

Since my playback is officially down I decided to give up my PP2000 for a local audio guy. He guy live in rural aria but has notoriously bad electricity and for many years was trying virtually anything but still what I visited him he always had v...

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...

A local audio guy what live in city bought PP2000. I visited him last night to see how it worked. He has the newest version of PP2000 that he was waiting for 3-4 months or so. His newest unit has output circuit barkers, run at least with 3 times le...

Nice to hear that it eventually produces less noise. At least it becomes clear now that it was far from being as silent as they were so quick to claim.Do you know if they plan something for previous buyers of PP2000 ?I would love to ask them myself b...
