For what its worth...
I have a mostly Cyrus system (see sig) and have found a MacMini 2011 (into Wyred-4-sound DAC2) to be a fantastic source for hir-res music.
Use Audirvana Plus which is a software player which integrates withiTunes and replaces the "engine" but uses the iTunes database managment. Simple then to use Apple's Remote app on iPhone / iPad to control. (I also have a RealVNC server running on the MacMini so I can control it from any of the Windows computers in the house via RealVNC client - very straightforward but not absolutely necessary!)
The sound is beautiful.
I have tried just about every software player on both Mac OS and Win 7 (Macmini is dualbooted) including: Amara, Pure music, Fidelia, J River MC, JPLAY.... Although I wanted J River MC to sound the best as it has the best database management, I keep coming back to Audirvana Plus. On my system, sounds the best.
So I can highly recommend this as a solution. The "streamers" are just glorified computers IMHO.
