To be honest I have no idea, I basically always use the Dragonfly 1.2 with it because the form factor is so perfect! The DF really only works via the UAPP app, which more or less limits it to local play only, however with a 128GB card in there I don't feel too limited selection-wise. It can actually stream from my NAS and work with UAPP, however you can only select one track at a time that way, so I have to really, REALLY want to listen to a song not amongst the 90GB of music on my card to bother with that.
I expect it'll be similar to all the other phones with Snapdragon SoCs, as they all have the same DAC and all of the several I have tried sound very similar with the exception of the HTCs which have a superior onboard amp.
