Jafant, the Tesla Powercell makes the soundstage come alive and more 3D. The noise floor is lowered allowing more detail and fullness of the notes to pass through without sounding analytical. I can't think of anything it does wrong. It doesn't protect equipment like the audience in case of a spike, but I am not worried about that. Everyone friend who has tried the Powercell has purchased one. Add the Galileo speaker cells and it gets even better. This is by far the best tweak I have ever added. If it's child's play, so be it, it sounds awesome.
