I separated my two of my PP2000 in my rack with 3 feet space and run everything from one PP2000 and both Milq power amps from another PP2000. I also routed the incoming power cords that that are far from each other and far from outcoming power cords. Each of incoming power cord is loaded with 3 large ferrite chokes. It looks like in this setting the things work. Whatever sound I have I do not feel tempered to roll of my tweeter for a 2-3dB and my MF for 1dB.  The Sound is pretty much as feel it has to be.

It looks like the problem of multiple PP2000 is resolved, BTW, both PP2000 are plugged in the very same wall outlet. The PP2000 that a drives Milqs is load with 50% and the PP2000 that runs front end with 40%. Another day when I have mood I will measure PP2000’s outputs in this configuration and will sniff with EMI sensor, trying to find out where and how  stray noise is coming out of PP2000 box. It looks like I have no use for my third PP2000 as I have no room to put it far from the rest PP2000 and in functional proximity to what it needs to drive. Perhaps I will find a configuration with three PP2000 units but I need to answer the main question of this experiment.

The main question of this experiment is following: does multiple PP2000 unit provide any sonic improvement over one single unit (considering that I can driver the whole system from one unit) . I do not have the answer to this question.  I do not have feeling to do the critical listening today. I will of cause as time come by. As today my sentiment is that two PP2000 sound a bit more dynamic then one, perhaps no dynamic but louder during load passages. This is very premature and I am sure my opinion will change 2509852 times during next few days/weeks… I will do more or final evaluations when I have my ULF amp with passive line-level filters back into duty.

A few words in the end of this little saga (do not worry more saga will come).The folk who follow this thread are witnesses all my ups and downs with PP2000, including the major fuck up that PurePower had in the end last year with new revision of PP2000. The question that a few folks asked at this site was why I demonstrate so much perseverance trying again and again to use PP2000 and trying to get the best out of it. The answer is ridiculously simple –Sound. When PP2000 properly operates and playback is organized with respect to sonic advantages that PP2000 offers than Sound is spectacular, truly is.  If I insist that I do not see my playback without using PP2000 then I do it not because I am trying to sell you PP2000 as some simpletons might feel.  In my view PP2000, although is does help with electricity (not completely)m but in reality it is not just a power treating devise  but rather a power sourer that makes audio to sound better. I very much like and in a way am addicted to the sonic contribution that PP2000 has. I consider it the sonic contribution in very proper direction.   I still do not attribute sonic benefits that PP2000 offers to PurePower as a company.   I do feel that sound of PurePower generators is an accident, happy accident and I am glad to be a part of it.
