for a 5.1 speaker system like z906, how big is the difference of the sound when using an analog cable VS a digital cable? I am using creative XFI titanium which actually has optical out, just wanna know whether there will be clear difference if i switch to an optical cable.

if so, can recommend me a good optical cable and where to get it? and i need to get 2 stands for my back speakers, where can i get that or it has to be customized?
