If you are just streaming, check out a Wiim Mini or Pro as the streamer and look into AudioEngine speakers. Good performance at a great price. I set up an office system with a Mini and the AE B2 and connect them with Bluetooth. The B2 is a one-box speaker so is great for a dorm room or small bedroom. The also have several other stereo pair options that you could use.
Looking for an all-in-one just-add-speakers streamer for my son to take to college
Cambridge Audio Evo 75 is probably the top of the range, but maybe a BlueSound Powernode is good enough? Maybe there is something cheaper that fits the bill?
My son is not (yet) an audiophile, so sufficient volume may be the most important, but interested in any thoughts folks have on this topic.
