Post Subject: Not surprisedPosted by Lx_ on: 8/21/2014

Hello Romy,

I am not surprised by your report, since I have experienced this with my PP2000. I must have shared this here already but here goes some of it. I can hear many things behind the PP, the amount depending on the equipment. Switching PSs are indeed quite noisy. I can remember being horrified when I discovered how much garbage a Dell PS was injecting into the mains and through the PP. At the time I think you were incriminating a faulty PP unit and/or installation. Maybe the issue is greater for non-US units, one of which I have (EU). But since you now acknowledge the issue at your place, this factor may be ruled out (though by how much I do not know). We must also take into account that you have a newer unit, and only PP people know what impact this has regarding sensitivity to AC mains (or at least we wish they do).

Anyway I have been disconnecting as many devices as is convenient (though not including a switching PS, the fridge is quite noisy too but I prefer getting some noise than salmonella or other nice bacteria) for several years. In the end, the best solution would be to unplug the PP from mains altogether (thereby getting rid of its internal charging circuit that does its own radiating), though I would need to hook several additional batteries to be able to enjoy a few hours of continuous (ecstatic) listening.
