FWIW I got my own PP 1050 a week ago and am pleased with the sound. It is the first active device that sounds as good as or better than my jury rigged passive filtration. Thanks Romy. As for chaining devices, I tried plugging in my VPI SDS into the PP 1050 and got worse sound than running it through the wall on the same circuit. I found that passive filtration After the PP 1050 improved sound however. Its worth trying the PS audio before the PP3000 but I'm skeptical that it will produce better sound. I guess you are now getting what Paul S and others have warned about. I myself started to notice sporadic unusually bad days for sound a few months ago. I don't know the cause but it probably was Dumb Grid shenanigans.

Well, it is difficult for the people who do not know what I mean to appraise what I mean. When I said that bad power I depicted above do affect my sound even my playback is driven by PP3000 then it need to be understood what I mean. I do not think that “Paul S and others” with their warnings are meaningful as they do not use PP and have no idea what they are taking about.

The reality is, and since you begin to use PP, that it will be very difficult or even impossible to remove PP from playback. Give yourself some time and you will see what I mean. To me PP is not just power treating gismo but absolutely default pre-power supply devise.  We do know that it still affected by incoming power. Well, like anything else. The chaining devices do sound VERY promising to me but it need to be a right devise. Knowing what PP does compare to any other power devise I tried I think it would be very hard to find a right one and very hard test it as it need to be tested only during the specific bad electricity days. My playback still sound fines during those bad very electricity days even those I can detect the sonic difference. Also, I did not have such bad electricity days for 4-5 month….

The VPI SDS is just frequency stabilizing devise. I do don’t think it will be affective before PP as the PP’s PLL will take care about locking to the any incoming frequency. You found that passive filtration after PP improved sound; may I ask you what passive filtration did you use? The good part of it is that most of the power devises are made with 30 days money back, so I can try anything….

The chaining the PP themselves sound to me like a good idea but chaining switching supplies would drop the power of each supply very drastically,  so I would need PP5000 to drive my PP3000 in order to have my 1.5K of pure power…. There is no PP5000… yet but I will be working on it. :-)
