Wiring isn't all that intricate or hard. Normal house wiring is fine, except the way they do it is daisy chain from outlet to outlet. This is fine for saving money on wire. But each outlet is extra connections, each of which introduces all sorts of little noises and problems that aren't there with one direct run of wire.
My room was wired the normal way at first. Later I ran a line direct. The difference was easy to hear, even with my system back then, nowhere near what it is now. It wasn't night and day, just your normal garden variety improvement you can hear.
Its almost impossible to AB this stuff so here's a simple test you can do to see if you even can hear a difference. Listen to music. Flip off a lot of breakers. Listen again. That's about the improvement you get with a typical AC power upgrade.
