FWIW, I had one of the original PP2000 units (made in Taiwan back in those days?). It certainly changed the sound - it seemed to add some 'sparkle' somehow. But I had an interesting experience with it...
I wanted to hear how thin...

[quote user="Paul S"] Didn't you first become aware of MF "problems" when you got everything else working better via the PP2000, and the MF wound up dropping back to weak sister status with respect to system-wide PP2000 benefits? [/quote] The PP2000 ...

Romy,I agree with the very nice summary you have made of the situation. You remember that I struggled for a couple years to get PurePower to return my PP2000 which had gone for repairs, but ultimately they replaced it with a PP3000+. I just have to ...

First of all this post is NOT related to the recent PP2000 problems but it has a border, general view.
The recent LX’s posts made me to think about the PP2000 buttery. He reports that his buttery got way weaken from 2009. I used my older PP200...

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...

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...

[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...

[quote user="Romy the Cat"] I know that this post will be lost in the jungles of my site and I am OK with it. Those who follow my site regularly will have a chance to read it not to mention that for me a message is not what heard by other what I ...

[quote user="drdna"] It is not exactly correct. There is 60 Hz hum eliminated by lifting the ground to the amplifiers. The neutral is connected to the ground prong and chassis in the amps, so I assume it is setting up a loop. However, there is a seco...

I do not know folks, I never was happy with isolation transformers. Perhaps I did not have the right isolation transformers but what I had was not good enough. Perhaps we have different electricity problem in my and your countries…. Whatever I had ma...

The Purepower state at their site that efficiency of the unit is 89-92% depending on load. I presume that they meant the power factor correction that need to be taking to the consideration. In my case my two 6-ch Melquiades run from two new PP2000. M...

I got today my second PP2000. This was the worst sounding unit, the one that I used for over 2 year, was fine then was upgraded to the new version and lost it sound. The first fix of the upgraded unit was not successful but this last one looks like m...

I was wondering what is coming out from PP2000 that makes one unit affect another. It might be radio and magnetic stray fields. Last night I took my gauss meter and was sniffing all around my PurePower regenerators. I was not able to see any signific...

This is very interesting subject that gave me a lot of head ache until I figured the things out.
It is known that I have aversion to ground that comes with mains. It is very dirty, so a few years back I drove 15 feet copper poll in pretreated backya...

[quote user="Romy the Cat"] Probably the whole thread about the evil electricity might be coming to it’s logical end…[/quote]Today turned the playback and I was surprise with gray and unexpressive bass. “What the hell?”- I asked myself. There wa...

[quote user="Paul S"]Truly desperate scofflaws might find themselves so annoyed by the hum that they lift the PP2000 AC ground connection at the PP2000 chassis and run that unit's ground only to a dedicated ground (with a lower impedance, of course),...

Since I go the new version of PP2000 two weeks back I was operating under presumption that they will be sonically similar tothe PP2000 that I have had. I did not invest time or efforts to confirm this presumption partially because at that time I was ...

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="scooter"] Indeed, this is a reference to how important electricity might be. After last night, I almost feel as though my equipment is a much less important factor and takes a backseat to everything else. At this stage, I am thinking...

Every day that I listen to my system, I thank God for Romy's perseverance with the pp2000. For the past 25 years I've fought the crappy electricity that comes to my house in the woods with everything from banks of 8 massive 2 and 3 KVA isolation tran...

[quote user="Romy the Cat"]First of all I feel that PP2000 is slightly “released” some HF.[/quote] The reported “softness” of PP2000 came with some HF roll off. I drive my MF amps much harder while I use PP2000 and it was a good help but still there ...

One of the most pleasant things about the Purepower 2000 (PP2000) that it in contrary to any other power devise I hear it has very limited if any impact to the original sound of a playback. Somehow the PP2000 surgically removes all negative manifesta...

[quote user="manisandher"]This is very disappointing to hear.
But in a way, it makes little difference to me. I had decided that I would only use the PP2000 from battery power when listening to music (or making vinyl transfers to digital). I'v...

[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” ...

Paul, I'm happy to compare the new PP+3000 to my old PP2000 and share my findings. The new unit has arrived in the UK from Canada and should be at my place this Friday.It's true, I didn't particularly like the sound of the PP2000 running from its reg...

A few post above Bill mentioned that he run his PP2000 from AdeptResponse power conditioner. I am not familiar if AdeptResponse helps to separate one PP2000 effect another. I am not also familiar with AdeptResponse itself. Looking it up it appears t...

[quote user="manisandher"] I'm assuming when you talk about the PP2000 here, you mean in AC regenerator mode. So what about in battery mode? Is it 100%, i.e. totally equivalent to "super electricity days" in your estimation?The reason I'm asking is b...

[quote user="Romy the Cat"] When I have my old transformer 11:1 then I had the midbass horns calibrated so perfectly that you can tune a large symphonic orchestra by it sound. It was spectacularly stop-on setting with any type of music if played it n...
