It is not exactly correct. There is 60 Hz hum eliminated by lifting the ground to the amplifiers. The neutral is connected to the ground prong and chassis in the amps, so I assume it is setting up a loop. However, there is a second problem of higher frequency hum which is eliminated only when the PP2000 is unplugged from the wall and runs from the battery. I think my thought would be if there is some way to treat the AC power input to the PP2000 to eliminate the second hum.| Paul S wrote: |

No question that the PP2000 and its good electricity dramatically change the presentation of the sound. It is too early still to be able to begin to explore in what way the new "good electricity" system must be approached, although I hope I can be allowed to enjoy the stereo in the interim. The sounds continue to change from day to day. The HF is still not returned, but I have not given up hope yet.
