Post Subject: My experience with original PP2000Posted by manisandher on: 12/8/2020
FWIW, I had one of the original PP2000 units (made in Taiwan back in those days?). It certainly changed the sound - it seemed to add some 'sparkle' somehow. But I had an interesting experience with it...
I wanted to hear how things sounded with/without the PP2000, so one day I disconnected the whole system from the PP2000 and plugged it directly into the mains. What I found was that it sounded pretty much the same! But only when the PP2000 was powered up. Switching the PP2000 off, the sound changed back to how it normally sounded. Switching the PP2000 on, and the sound changed to more 'sparkle'.
What I concluded was that the PP2000 was emitting some RFI that somehow interferred with the electronics in the system. I stopped using the PP2000 with my system after that and used it as a regular UPS with my work PC instead. When its batteries failed (a few years ago now), I dumped the PP2000 in the trash. I haven't missed it at all.
Mani.
