I appreciate showing me the alternatives. Looks like for offline play, there is effectivly nothing else (everything is software based). I'll most likely just get a topping nx7 to act a the amp, and run 1.4v from the 5k SE (the minimum voltage the nx7 needs to run properly). Its battery is 8 times the size of the qudelix, so if that doesn't work, then nothing will. Thanks again.
