Hey, there's no need in jumping to condescending assumptions. You need to daisy chain the LC in any configuration since it doesn't have its own dac, I'm just curious how the dac in the mojo would sound. Also, since the mojo has a line out setting it conceivably could be used solely as a dac for any headphone amp.
Believe it or not, then there are DACS out there that can not drive headphones on their own and actually NEED an external headphone amp to fulfill that purpose.
With respect to others, then I can understand the need for an LC if you have to play very loud. Just take care regarding how long and how loud you listen. There is no point in audio equipment if your hearing is gone.
