Hi. Thought I'd post my question here first as you guys seem to be the ones that woudl best know. I've done some searches, but nothing came up for what I'd like to know. This question may be a bit novice, so if it needs to be moved please do so. What are the pros and cons (if any) of getting digital speakers over analogue ones? Shouldn't all the decoding (5.1 / DTS etc.), be done by the software on the computer? I will just be buying a standard mac pro with no additional high performance software / hardware. Thanks!
