Very interesting information on the Powerplant’s AC noise attenuation/filtering abilities - Paul says that PowerPlants don’t attenuate much line noise above 1kHz. > [@Powerplant peak current and noise filtering Capability](https://forum.psaudio.com/t/powerplant-peak-current-and-noise-filtering-capability/18560): > > @Paul or @rower30 or any one from psaudio or any community member who can chime in i have a few questions on the capability of the psaudio power plants The powerplant say p12 or p15 or p20, does it have the capability to provide more peak current compared to a wall outlet? asking about this because since the regen involves AC-DC-AC , does the power plant have more storage capacitors to augment for peak and transient current requirements say for a power amp needs? does powerplant have a… --- _[View the full topic](https://forum.psaudio.com/t/power-plant-and-noise/8813)._
