AFAIK, it should be the same as the toslink. You can try the optic fiber ones muna. I know there are glass fiber talaga kaso it's expensive. One thing i've learned from master Shifu Stagea, your toslink connection (the one in your transport and DAC) should be capable of transmitting and receiving 24 bit signals if you plan on using it for studio master recordings. I've tried both digital coax and toslink, there was no distinct audible diffrence in my previous system, perhaps because it was just a short run (1 meter).
