Very dependent upon transport/DAC combination. I've had both terminations work best in different setups. In my experience AES/EBU cables have a little more air and/or warmth in mids and bass, this added air/warmth has been problematic in one setup as it caused a bit of bass boom.
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
