Mitch, good question. I'm running a dac and integrated amp off a 12v car battery and the experience has been nothing short of an audio revelation. My source is a laptop which I run off the battery so the whole system is off the grid.
The amp can only output about 10 to 20 watts from the 12v, but the power delivery is huge since there's a huge power reserve in the big battery. The sound is crystal clear with huge authority & control. You need a pretty efficient speaker. My speaker are horns. You could bring in another 12 volt battery and double the voltage to 24 which would double wattage to 20-40 watts, and on & on...
The dc power is immediate - there's no ac to dc conversion so there's no need for the big and noisy transformers (this is where much time and money goes to developing hifi gear-quieting the power delivery through the transformers). I'm not too knowledgeable on the technical side of this and hopefully another member can comment on the mechanics. I'd recommend giving it a try.
