I fully agree with the remarks posted by George above.
Speaker cables certainly can make a difference in the
sound of your system. So can speaker placement, the type
of interconnects you use, and the various components in your
audio system. Mostly what it comes down to is matching the
right components with the right connections. It certainly
helps a lot if you have rather revealing speakers - such
as Wilson or Thiel - which tend to show up the shortcomings
in your sources or interconnects.
