I believe the power cord is the most important cord in my system. I've also come to the same conclusion that it has had more impact than changing speaker cables and interconnects. In simplistic terms, our systems turn power into music.
All the downstream cables (speaker cables & IC's) benefit from having quality power. One must tread carefully though as it can become really expensive if you get the itch to change all your PC's at the same time. I took my time and I also use 3 different brands (mix and match approach) instead of a complete loom as its more affordable. I've also found it's best to experiment, there is no fixed set of rules. My 'best' and most expensive power cord sounded better from the power conditioner to my integrated amp instead of from wall outlet to the conditioner so I kept it there.
If you haven't read Nordost's Foundation Theory please do so as it made me think differently about how to optimize my system and how to get the most satisfaction when I do upgrade.
