if you are using the headphone jack on the computer, converting that using a splitter into a pair of RCA wires, then running the RCA straight into the low input for the amp......no you don't need a DAC. the headphone jack outputs an analog signal. this is what I have been using in my car for quite a while, and it seems to sound fine.

if you get into really high end speakers or if your signal is going a very long distance, that is when you may want to consider running a digital signal either to a DAC or to an amp with an integrated DAC inside it. Wires for that could be a good single RCA or optical.
