I will very soon have three devices that output digital audio via a coaxial SPDIF (DVD, computer, and HD receiver coming in a week or so). Unfortunately, my receiver (Onkyo DS656) only has two coaxial SPDIF inputs. The lone optical input on the receiver is occupied by my XBox, so I can't incorporate that into a solution. So now I need a switcher! Can I just use one of those radio shack composite video splitters for this purpose (~$25), or is there some bandwidth issues that would prevent this solution? Since I plan on upgrading audio receivers within 12-18 months, this switcher will be a somewhat temporary device. For that reason I don't want to spend a lot of money on a top of the line product. On the other hand, I want minimal quality loss. Any ideas for solutions are appreciated!
