This allows the user to make use of the DAC's power-saving abilities. The two modes are "high performance" and "battery saver". This feature is supported by the AK4376 DAC in the upcoming FiiO M3K port. The setting is only a manual toggle right now, but in the future it could be hooked up to the battery level (via another setting) so it can be toggled automatically when the battery gets too low.
