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.

Romy, how do you power your DAW?

I power my DAW from PP2000 as everything ease. I convinced myself to do it from ground considerations. You I have two ground – external and internal. The external is what the PP2000’s inputs are pumping dirt into. The internal is my audio gear is clean and end up with 15” copper poll in backward via 1ga cable. To run PC from utility line it means to use utility dirty ground. I run single ended wiring and my ground is my negative signal terminal, my Milq’s cathodes are sitting on the same ground – I did not want to mix it with utility filthy ground. So, the only reasonable solution for me was to keep DAW on the PP2000 side, what the clean ground is. The next paragraphs read very careful as very few people including the PurePower people get it.

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.
