I made the 543rd remodeling on the Opera room and move the video playback equipment to the new, I hope the last location. As I connected everything into PP2000 as it use to be (not PP2000+) but older not “Plus” version than I have some light MF buzzing from loudspeakers. There is nothing wrong with the PP2000 as I use it for my main system for long time with absolutely silent operation. Now with only DVD player, Dish receiver, preamp and power amp I have noise.  All grounds are lifted and I wonder where the loop is coming from.  I will look into it further but it is kind of strange.
I would like to point out the post above as relatively important for the folks who use PP2000 as reported that it has noise. Now I have noise and on surface the noise dose come for PP2000. I have just 4 pieces of equipment that are absolutely silent from wall but then I plug them in identical configuration to PP2000 then they do have noise from speakers. Obviously it is PP2000 fault. Even despite the fact that the very same unit worked in my main system for 2 year but now it has noise and presumably it is “broken” and needs to be send back to Pure Power to “fix”. Well, I think that this is all crap and there is nothing wrong with my PP2000, even though the noise is there and I cannot get rid of it for now. I am very sure that there is something that I am overlooking in this very simple configuration that is responsible for the loop, I just need to find that something. I will be looking deeper into the reasoning within the next few days and will post findings.
