Sorry if this is a stupid question, but I haven't been able to find a straight answer anywhere. Does the odac+o2 DAC/amp combo run off batteries, which means I can take it with me on the go and use it with my phone, or does it require an AC power source? Also, how big is it? Will I be able to carry it around with me without too much in convenience? Thanks!
