I thought cyanogen mod included the USB_AUDIO "drivers" already, although I'm not an android developer nor do I know too much about the insides of the OS. Does this mean that DACs that require more power can be used? Sorry my limited knowledge of android prevents me from comprehending half of what is in that thread.

Some bus-powered USB DAC like the Objective DAC (ODAC) can be powered by some Android smartphone like the Samsung Galaxy S III.
If a bus-powered USB DAC requires too much power, it should be connected to an Android device via a self-powered USB hub.
And a clean 5V battery-powered USB hub could improve the sound quality:
