PS Audio PowerPlant P20 better than pure direct AC I get during the night?

So Elizabeth your experience says the variations provided by an AC accessory (from cable to regenerator) are impredictable. A technically advanced component designed to improve AC may also slightly change the tonal balance and that could be welcome or unpleasant to my ear possibly at a higher level compared to the "base improvement" it will certainly give.

I really need to audition the P20 in my system before buying.

Thank you for your help!

I used an AC regenerator once, (PurePower,) and it always had warm up changes, because it really is an amp set to 60 Hz inside.

Switched to a Chang LIghtSpeed line filter. and found that much superior. At $1300, not thousands.

Dead silent, 3D, warm sound.

Bought another for my home theater, and the HD picture vastly improved!

I never had a good outcome with PS Audio...always closed in the sound
