I was/am in the same boat. For me my goal is to get my macbook pro out of my music system, to access my music library from an external drive or nas, and to move into streaming. I was looking at aurender, oppo sonica dac, w4s modified sonos, green computer and sonore, bluesound and auralic. I ended up ordering a bluesound node 2 primarily because it seems to have the most streaming options. I dont want my hardware choice to limit what I stream and for some strange reason even the high end servers seem very limited in what they offer. Bluesound and Sonos have the most I am just turned off by sonos' lack of hardware refresh. Just ordered it last week so I cant say if it worked out or not. Good luck.
