Maybe I'm a "tin ear", but I'm damned if I think the coax is a distinct improvement over TOSlink. I have a DVD player that has both types of outputs, so I can switch from one type to the other. There is a difference in the sound, but I'm not sure one is particularly better than the other. I'm using a very good quality digital coax cable, but bought the Monster Cable TOSlink for $40 to see if it was satisfactory. It uses glass fiber rather than optical-grade plastic, and is sounds fine to these ears. The way for you to find out is locate an understanding audio retailer who will let you try both types of cable and decide for yourself after listening tests. Bet you won't hear much difference either!
