Why Expensive power Cables when Romex behind Wall?


Could somebody please help me to shed light on this?
Is there any reason I should invest in expensive power cables when there's low grade cable between my outlet and the wall? I've upgraded most other components in my systems, but I'm just not sure that spending several hundred dollars for power cables makes sense, when the cable running from my outlet to the wall costs less than $.10 per foot. Can anyone shed light on this?

Thanks!

I always thought hospital grade just meant that it was designed not to produce any arcing when a plug is placed into the receptacle because of flammable gases that could be present in a hospital room?
