Digital RCA vs AES/EBU connections


If both the transport and DAC have RCA and AES/EBU connections, and assuming comparable quality cables are used for the 2, how would the sound differ? Which would you prefer? Thanks

I've made a few comparisons like this, and even though my eyes & brain prefer the aes/ebu standard connection, the rca imho sounded better in most cases.
I have always found digital AES/EBU connections to sound relatively thin in the midrange. I have also found that using BNC or true 75 ohm RCA connectors is a significant upgrade if you use the coax connection.
