For use in a headphone amp, li-ion and nimh batteries will function similarly. Both will be superior to alkalines because they maintain relatively stable voltage throughout the charge span; alkalines become progressively weaker. Since the HEADSIX runs only in low current mode (relative to the MOVE), the maximum voltage output is also limited and therefore no benefit will be derived from the use of a 9.6V nimh over a 9V battery. For the HEADSIX, the 9V li-ion is the best bet due to its greater capacity, 500mA vs. only 300mA for the 9V nimh.
