PS Audio PowerPlant, like everything else audio, is a YMMV thing.
"the PP is programmable to put out whatever voltage you want. "
The OP's model does not have that feature.
Power conditoner..
I have a stand by generator for my house. I've noticed when we have an outage & the generator kicks on the lights in the house are brighter. They are getting a full 120v. Because of this I thought a power regenerator would make a big difference in my stereo. I installed a PS Audio Stellar 3 Power Plant & I can't tell any difference. Oh well, live & learn.
