Are they relatively interchangeable? Will I be able to use some 110 Ohm Nordost balanced interconnects I have available or do I have to buy a specialized AES/EBU cable? What makes the difference? Is it the impedance, or somehow is it the wire/wiring that makes the two different? The Nordost sounds just fine to me now but would the other type of cable be even better? I will be using it with a Vivaldi DAC when it comes in the next couple of weeks.
