I received my P20 in May 2020. When I plugged most of my components into it, the sound was good but I had a hard time hearing the difference from when everything was plugged directly into the wall. The P20 was plugged into a dedicated 20amp line using a Shunyata Sigma NR 6' 20 amp power cable.
Then recently, I watched a video on Jay's Audio Lab's YouTube channel where he compared the sound, using the P20 with the Shunyata Denali 6000 and reading a PS Audio forum post where a user claimed unplugging everything from his P20 and into the wall outlets made his amps come alive. I then unplugged everything from my P20 and plugged everything into my wall outlets. The sound had more detail with more dynamics. The change wasn't dramatic but it was noticeable enough that it prompted me to sell my P20.
I'm now plugging my components directly into the wall. I have 7 dedicated 20 amp lines running from my home theater to a dedicated service panel with a copper bus bar, using 10 gauge shielded wiring with Furutech GTX outlets so my power situation was pretty good before my P20.
However many people do report that the P20 dramatically changes their system for the better. Possibly the P20 is better suited for systems without dedicated lines and run appliances from the same panel while they use their system.
Good luck with your decision.
