Unfortunately it's much more complicated. You'd still need to regulate the voltage as a battery's voltage is higher fully charged and gradually lowers as it empties. A high quality low noise regulation stage is expensive and requires many parts. Also batteries aren't as noisefree as many people think and their output impedance is higher than a good linear PSU and varies with it's remaining charge. You'd also need electronics to charge it. Batteries age and with it their parameters (capacity, output impedance etc.) change.
Good power quality in HiFi is of the utmost importance and expensive, there are no shortcuts only compromises.
