Alright, this sorta sucks.  I went to Fry's yesterday and tried out the Z-560's.  After looking at them, I see that they have no digital input.  I found out that a friend's brother has the Z-5300's.  Those have no digital input.  The Klipsch's, according to some of the stuff I posted above, have digital input but it doesn't work with a Crative Sound card anyway (which I have).  Is there ANY way to get actual surround sound without being forced to buy Creative speakers?
