I spent $300 for new wall sockets and PS Jewel power cords... some here pay that for a single interconnect. The audible difference in base performance and reduction of irritants in sound was well worth it.
Having done electrical construction long ago I strongly suggest anyone start first with replacing the wall sockets with heavy duty sockets...the plug in your wall is likely the cheapest garbage possible and you won't benefit much from connecting a heavy duty power cable to a pot metal wall socket.
