Yes, battery power can work very well. The T1 and T2 amps sounds really good powered with 2 x 12V SLA batteries to get 24V. For the cs4398 dac you could use two 12V batteries. Battery type will affect the sound, so you could experiement with differnt types. And yes, those output cap will also make a big difference.
