Post Subject: The second, upgraded PP2000 is in and upPosted by Romy the Cat on: 3/4/2011

I got today my second PP2000. This was the worst sounding unit, the one that I used for over 2 year, was fine then was upgraded to the new version and lost it sound. The first fix of the upgraded unit was not successful but this last one looks like made it.

I have no idea what PurePower did but it does not sound gray anymore. I did not do the final testing but I think it will be accept able this time. If it did then I juts will add to the second unit the extra capacitance to the battery and my current PP2000 has.

Meanwhile, the presence of the 2 properly-operating PP2000 enable me to finalize my power layout and do what I was curving to do for months – to finalize my grounding schema. As now I have 17 power devises. Listening the grounds very careful and changing grounds for some comments I was able to make my playback absolutely silent. It means I can stick my head into MF horn I hear not only no nose of any kind but I cannot even say if the playback is on. With 109dB sensitivity, 14 active amps and a shit of other electronics it is not so simple.

So, what I have now is one PP2000 running all time with only sources and lower bass amp plugged into it. Then I have both of my Melquiades driven from a separate PP2000. This PP2000 I turn one and of when I need it. In fact I keep the Melquiades power switch on and use PP2000’s switch. In future I might review how my PC plugged into my source PP2000 affect Sound and I might decuple it f I feel a need to it.
