I think a dedicated digital source cable looks a lot nicer than a stock power cord.
I like signal cable

Some people may think they are just regular cables that look good, but I think they are really good cables that look great. I am not much of a beleaver in super expensive power cords though. Remember the other side of the outlet is most lickly romex back to the panel so as long as you match the same gage or larger that is going back to the panel you should be all set.
