Best Option For Audio Cable: Toslink, Dig. Rca,Etc

Besides using the HDMI for audio, what is the best option to be used for listening to tv/movies and music??

I currently am using Toslink for my tv/movies and music.

Any help would be appreciated.
I use analog cables for music and digital cables for Movies/TV. Theres arguments galore for using Digi over Optical or vice versa, but in the end its just sending 1's and 0's. I think either way you are fine.
