Every piece of literature I've read says that the coaxial connection is better sonically than the fiber optic. Sorry, I don't remember the reasons. My Madrigal manuals recommend (best to worst): xlr, bnc coaxial, rca coaxial, glass. High end stuff doesn't even offer glass.
Is AT&T a Good digital cable connection ?
Does anybody have experience with AT&T glass digital cables ? Is sit a better connection than coxial ?
