You are going to have to experiment. Some manufactors provide better optical connections than others with some neglecting the toslink because the coax is more common. I observed exactly what you have read though in my system with the Toslink being more liquid but it lacked the detail of the coax. I was suprised to find that I actually prefered the 40.00 Lat International tollink to a 160.00 Wireworld silver starlight coax. I am using a Calfornia Audio Labs surround processor for digital to analog conversion and a Pioneer Elite dvd player as a transport. This is counter to what I have read should be the case.
