Personally, I would finalize and break in my components before spending a significant amount of money on cables. Otherwise you are just optimizing the sound for components that will be changing in the near future. If you feel compelled to buy something, check out the Signal Cable digital power cord and silver IC's. Very good products for the money and not so expensive. Don't get me wrong - some expensive cables can yield transformative changes in a system, but I think you should match them to what you have - not what you are going to have. IMO.
