Looking for an all-in-one just-add-speakers streamer for my son to take to college

What about a SONOS Play 1?  Or a pair of them?  

+1 for Bluetooth speaker. It kind a complicated to build and maintain audiophile environment with in college style of life. I suggest something like Harman Kardon HK SoundSticks 4-2.1 Bluetooth Speaker System. Nice build high quality BT system, pretty universal. Could be used with phone streaming or hardwired with computer, provides deep reach regulated bass. 

OP didn't mention budget, but I am very pleased with Arylic for my "not the main system"  $153 on sale

i have their streamer on a PA system in the garage.  I also have their bluetooth 50W amp driving some Boston Acoustic CR7 on the porch .  The link above is streamer plus amp.  I don't have the latest BT source (iphone) so when I say that  BT sound is just "ok", maybe that is dated.  The 50W amp sounds very good with an ifi DAC on the iphone and its analog inputs.

Streamer + powered speakers, or streaming amp with passives.  

NAC C700 would be as high up as I'd go. :)
