difficult to say,because diffrent (brands)media server has influence to the sound too.I tried 2 diffrent cd players with the same toslink glass cable and the sound is a bit diffrent ,one is bassier than the other.What makes the diffrence? I don't know.Anyway good toslink cable will let hear what recording is like.With good recordings you will enjoy the sound,with bad you curse cable. With coax you can choose what kind of flavour you want paying megabucks or several $
