BUT will the PP2000's and the PP3000+ still make the interference even if not in the same system, even if just plugged in for a completely separate stereo system (or toaster, etc.) in another circuit breaker?

Yes, it is what I discovered: they do affect each other even in case of another circuit breaker. The only way how I did not hear impact was to set 2 PP to run on the different sides of 220V line, of as we call it in US on the “another phase”. The problem with it that one of my 220V sides do not sound good, so why to bother. I am not too serious to sell my PP2000 unit. I do not use it at all and it sits in there just because it is tested and it sounds perfectly. In case my something happens with my PP3000+ unit and PP got for another “episode of randomness” I will have a PP2000 to fall back.

Interesting. It has always been my experience (as reported here already) that as outstanding the PurePower is at improving sound, it still is sensitive to input AC. This is contrary to what the product description would have you believe

Lx, if you read this site that I will see that I made very many comments on the subject. Of cause the PurePower is sensitive to input AC, like anything else. The improvement the PP does might or NOT be related to the AC distortion corrections, after all we have devised that generate no distortion AC and that sound like shit. It is might be a very stimulating to investigate but I am not so much prepared to spend another 30 years of my life to think about it. To the best of my knowledge there is no definitive answer why PP sounds as it sounds, in fact why any of AC correction devised sound as good or bad as they are.

Why did I mention ProPower?   Because after my experience with Richard, I am beginning to believe that ProPower is the real one (including that they were the original engineering designer who created the AC regeneration circuitry). 

 
I do not think it is the case, OracleAV. If I am not mistaken, PurePower adopted some kind of existing commercial unit, was it by the Chinese company of not I do not remember. The Chinese company you refer ProPower in past had different names and they were the company that build the units for PurePower. A few year they separated and PurePower assemble the things in house, while the Chinese company keep producing audio regenerators. I am pretty sure they hardly know what their products might be used for in audio and I would extend too much credibility to what they do. They are perhaps a good electronic company and do wonderful toasters for Walmart but I do not think that they have any audio objectives.
 
Regarding the rest of your straggle, OracleAV. I do sympathize you but try to understand: this is site has audio sonic objective and your frustration with PurePower is neither entertaining nor enlightening. Most of the people who dealt with PurePower had “issuers” so, what? I do not ask you to stop badmouth PurePower, if they did wrong things then they dese own share of negative publicity and you feel free to post anything you want. Still, you will not surprise anybody at this site with the fact you have “issuers” with PurePower. However, if you do get the properly working PurePower and do understand the sonic benefits it offers then you might understand where drdna  and another are coming from.
