I can't give you any help on Sonus Systems, but i was shackled to iTunes until last year when i moved to J River Media Center and JRemote (iPhone APP)
I was tired of converting all my flacs to ALAC, so i got off the iTunes. Not running flac and not being able to switch from 16 bit to 24 were the
deal breakers for me.
I have all my tracks on my main music computer (90,000) where i run J River Media Center. I can control everything remotely from JRemote

i can stream any of my 90,000 tracks to the apple TV > dac > preamp > amp > speakers
In my main music room, i just sit on my couch and browse my tracks on my iPhone and cue up stuff to listen to.
For my bedroom listening i bought one of these Altec Lansing iPhone docks for 69.00 that sound fine for casual listening,
but still have access to all of my music through the iPhone.

and access my 90,000 tracks over the internet using JRiver Media Center media server functions. My friends freak out when they get in my car, because i can access any of my recordings
right from my iPhone.
Theres more ……when i'm at my work computer (where the high end headphone setup resides)i have a second instance of JRiver Media Center running there and i can load the library from
my main music computer on my work machine via my home wireless network and play any of my 90,000 tracks on that computer as well using JRiver's DLNA setup.
And when i'm laying in my chair out back i have access to all the tracks and listen with my Shure SE535's on my iPhone.
