Enjoy your listening...
A DAC is the piece of hardware that converts digital signals to analogue so it produces music/sound. The Touch has its own DAC, but you can bypass the internal DAC using the line out on the Touch with specific types of docs.
My guess on the flat settings is that EQu and the Touch are calibrated differently on their flat (no EQ) settings. But that's just a guess.
An equalizer? Let me google that for you ...
