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!

This is an excellent question but that 6 foot high-end power cord can make an audible improvement. This similar to using high-end speaker cables. Most internal speaker wiring is tin-plated copper yet one can hear an improvement. There are many claims of how power cords achieve this sonic improvement by filtering, shielding, and lower inductance. Of course there are many so called high-end cords that make no improvement at all (IMO) so be careful in your selection.
