Bruce, the Motorola does hae something labeled: optical SPDIF, it is an orange rca jack but it next to the "audio in" jacks. in a row underneath the SPDIF jack are 3 rca jacks; a green one labeled "y", a blue one labeled "Pb" and a red one labeled "Pr" but no toslink output.
On the back of theCary unit there are both in/out puts labeled coaxial (rca jack), a toslink, and a balanced AES/EBU (what does that stand for?) any way, on the front you can switch from the CDP to any of the 3 digital sources: AES?EBU, coaxial or toslink. So, what do you think? Should I just try hooking up from the Motorolan RCA SPDIF jack to the Cary coaxial jack? thanks, jb
