Here are some more conceptual overviews on power system concepts and optimization for audio from the same manufacturer. Full disclosure, I own some Shunyata products and currently like and use several of them, but have some in the box, replaced by various power cables assembled by me or a small vender on Agon that provide high value at a reasonable price point. This is not an endorsement of their products, just a reference to what I see as some sensible and simple descriptions of how well designed power products do their job to improve overall system sound.
