Since most of my music listening is done in my home office I have two setups:
Headphone: iPad or iPhone 6S+ -> NuForce iDo DAC -> iFi micro iCan -> Senn HD650s. Typically steaming Tidal
Speaker: Mac air -> AQ Dragonfly 1.2 -> Focal Alpha 50 monitors on isoAcoustics stands. Stream Tidal, saved FLACs, and iTunes with BitPerfect
Either setup is great for listening while I'm working and not in meetings that is. I need to take a pic and post once the work clutter is off my desk.
