I haven't compared aes/ebu directly to an xlr interconnect but I was using the Acoustic Zen MC2, rca on one end and bnc on the other, and tried using a .5m Moon Audio Silver Dragon (xlr) in its place (between a Red Dragon S500 and Audio Alchemy DDP 1). I prefered the Silver Dragon and have used it there since. I also tried the 6Sons Audio Golden Eagle interconnect as a digital cable and it is even better so yeah, you can go with a simple balanced interconnect and get quite good sound. An aes/ebu digital cable may sound better but I am satisfied with this for now.
