If it is a good quality cable I suspect you will have difficulty hearing a difference between it and most, if not all, digital cables. To answer your question, it is not detrimental to your equipment. Only by listening can you determine what is best for you.
Important Interconnect Question
How detrimental is it to not have a digital cable connecting a transport and a outboard dac? I was sold a analog interconnect by a dealer with whom I have a long standing affliation. I'm a bit embarassed to be even asking this but i assumed I was buying a digital cable. I'm not a 100% positive but very suspicious. I'm going to check when I get home.
