I have an iFi Zen Stream, and cannot recommend it enough, but, you do not want other equipment, nor does the Zen Stream connect *directly* to Apple Music via AirPlay. Yes, you can connect to it, but AirPlay limits the file resolution to CD quality only.
Thus, if you have the wireless dongle for the 105, your best bet at this time, would be to use that and connect Apple Music via AirPlay.
