Yes, in principle a power regenerator should do the best job. However, a good one, with sufficient output capability to power an amplifier and other components that may draw considerable current, will cost considerable $, and also be substantial in size and weight. The leading example that I know of is the PS Audio Power Plant Premier, which costs $2200.
And even for that unit you can find comments here from some people who found it to do more harm than good. I have no idea why that may have been so, assuming the current draw of their system on high volume peaks does not approach the regenerator's maximum capability, but like a lot of things in audio there are effects that are inexplicable.
