Be careful with Signal Cable, I tried using their power cords (amp & digital) and initially I thought that the cables made a big difference, but after using them for a little longer, I realized that all it did was change the sound signature. My system was no longer neutral in sound. I put back on the stock power cord and everything when back to what I remembered it. I would recommend Pangea power cords, they are also relatively inexpensive, but from my experience they keep your system neural. I can't speak for Signal Cables interconnects or speaker cables since I never tried using them.
