HDMI VS. component

I have a digital light projection Sony 60" TV. PS3, digital pvr box. I am looking to upgrade the cables and am looking for suggestions.
The Wireworld HDMI cables are a no-brainer.
thanks for the lead
Why do you want/need to upgrade the cables?
I don't need to. This just becomes the eternal search for perfection. I have a tube audio habit that has spilled into everything electronic lol. I have learned that sometimes it is worth spending extra money for better quality and sometimes it isn't. I just want to leave no stone unturned. To know if I spend some extra money my viewing quality is going to increase for me that is worth it.
