I had been using the cable supplied with the transport to connect the DirectStream memory player with the DirectStream DAC with a Wireworld Silver Starlight HDMI cable, and to my pleasant surprise, it improved the sound quality a bit. The sound stage, placement of individual voices and instruments, and a slight improvement in the "sweetness" of acoustic instruments were the main things I noticed immediately.
All my other interconnects are Wireworld Silver Starlights, happy with all of them.
