How do you know when to use ANALOG vs DIGITAL?


I'm struggling to understand what type of interconnect I would use between my pre-amp and my amp? Is it an analog signal?

I'm assuming that I would use a digital going from my source (DVD/CD) to my pre-amp?

Just a little confused? Thank you for the help.

Dekay: I tend to "favour" the "olde English" spelling variations of several words. Having said that, i typically say "aluminum" even though it was originally called "aluminium" by the English : ) Sean

You answers are definatly very scientific, you have the verbal accuracy of a 30-06 with a high powered scope.

Keep yer explanations as they are, mine are dumbed-up enough, it is nice to get an answer that goes more in depth and explains a little more.
