This may make sense for analog devices, but not in the digital world.
Unless the source is badly mastered it is impossible to increase the
volume by more than 10%.
The bias towards lower volumes seems very justified to me, as lowering
the volume causes hardly any problems, while rising it will cause artifacts.
Actually the right solution would be to setup you amplifier to a high
enough amplification and only _decrease_ the volume with filters ;-).
