Extremely short S/PDIF cables whose impedance is NOT properly controlled to 75 ohms can create signal reflections between source and DAC. These confuse the DAC's clock and cause clock jitter. The sonic result is a loss of focus and, well, timing.
If one has no idea whether impedance is controlled properly in any of source, cable and the DAC itself, it's best to go with a coax cable 1.5m long. This gives any reflections time to travel down the cable and back slowly enough that they arrive at the DAC offset from the true signal step.
