This will probably system dependent. In my own system I have compared AES/EBU to BNC terminated SPDIF cable of the same brand and I prefer the balanced AES/EBU. I have also read others who prefer the SPDIF. I would suggest you try both, if you can borrow a cable to try out, and then decide.
Is AES/EBU digital cable/connection all that?
In my current digital front end (transport,dac)I have the option of AES/EBU or regular single ended(RCA)digital coax. The digital cables I own are all single ended(Green Hornet and Illuminations D60 cables).Would it be worth the cost to upgrade to AES/EBU cable? Thanks,gixerman
