I have tried using a pair of balanced audio interconnects (Transparent) going from transport to DTI 2.0 and from DTI to DAC. It did not work. The soundstage collapsed. The midrange took on a recessed/veiled sound. This was not good. If you want to play around with balanced digital cables either pick up some used ones or try the Apogee's. They only cost around $30-40 and you can get them at Sam Ash (Pro Audio Dept) with a 15 day right of return. The Apogee's are not the most tranparent digital cables around-they are somewhat grainy, but they can sound forgiving and may work well in the right systems. I have also tried the Van Den Hul analog rca cables as digital cables a couple of years ago when I believe Stereophile recommended them, but they didn't work either (as digital cables). I am not a techie, but I believe there is something about the 75 (or 110) ohm spec that affects how the bits and bytes flow thru the cable.
