Did anyone return a PSAudio Powerplant? Why?

I tried a PSA Stellar PowerPlant 3, but eventually sold it.  I actually had an entire PSA Stellar stack.

Anyway, I was looking for AC mains noise reduction, which the PP3 did not provide (as already mentioned by others here), so I let it go.  What really helped me with noise reduction was a Puritan PSM156 power conditioner.  I checked results with a simple EMI noise meter, and the difference using the Puritan conditioner was measurable.  The Puritan also touts blocking DC, but I think you have to have quite a bit of DC present in order to notice a measurable difference.

Tried a PowerPlant 3. Did nothing for my system. Returned  it. In fact it made my soundstage slightly darker and less wide. Depth was good. I actually think my power is pretty good from the wall. Can’t detect noise, hum etc. My system when on and not playing anything is dead silent. Total blackness. Don’t think I need anything. I did notice some harshness in the lower treble during the last heatwave when power was in high demand but since I upgraded my sources both DAC and Streamer’s power cords to 10 gauge that solved the problem. 

OP,

Thanks for sharing your experience.
