When I first got my BDP-1, I had an old 110 ohm digital cable by XLO that I had used previously - and successfully - with other hardware. When I used it with the BDP-1 into my DAC, I was not pleased with the dynamic range. Bass punch was lacking - the sound was thin. Since I had Straightwire cables in the rest of my system, I called Straightwire's Steven Hill. He suggested that I obtain their 110 ohm Info-Link cable. I bought a 1 metre length. I am here to tell you that cable made a HUGE change in the sound, as in WOW. Steven said that with various combinations of hardware and digital cables, there can be signal reflections generated between sending and receiving units (BDP-1 and DAC) that can cause degradation in sound. He was absolutely right about degradation of the sound. The dynamic range is now wide open and the sound is so fluid, smooth, and wonderful. Soundstage and dynamic range are both expansive. So the choice of digital cable is CRITICAL based upon my experience.
One other point Mr. Hill made to me. He strongly recommended using the 110 ohm AES/EBU implementation where feasible because he said the bandwidth is much greater compared to the 75 ohm RCA or BNC implementation. So I have stayed with only the balanced AES/EBU 110 ohm digital cable. Enjoy!!
