Power cords are really pretty simple.
They are filters. If you can't hear any difference between power cords, you either are 1) blessed with pristine power, due principally to your location in the world, or 2) are cursed with some component(s) in your stereo that is such an underperformer that it masks the improvement the power cord brings.
I just switched from a $160 Pangea power cord on my Innuos Zen Mk III streamer to a $260 GR Research cord. At first, I was shocked. The soundstage collapsed from wider and deeper than my room to about 3' wide! It sounded like the music was in a tunnel. About 2 hours later (I'd left it playing), I was shocked again. The soundstage was back to it's original size and I suddenly had the most dynamic and tightly controlled bass I'd ever heard. It was not subtle. Better than much more expensive systems I've heard elsewhere. I couldn't stop listening for hours.
