Mr Soul...   as a noob,  I'd like to ask the question of the Digital I/O...
I have the D50 and the Digital I/O...  I don't have a cable for the connection... should I go with
the optical or the coaxial connector on the digital I/O..   whats the difference as to quality?
can you point me to the cable I need... 
and what program do I use with the Soundblaster to interface with the D50??
what do I gain by using the Digital I/O over the USB connection 

any and all information is greatly accepted 
Thanks
