+1 on AudioEngine. I used their A5+ powered speakers in my home office for years with a Raspberry PI Logitech Media Player streamer/music player. That combination sounds surprising good. I think their powered speakers would also work well with either their WiFi or Bluetooth streamers. And they also have a fairly decent subwoofer that can also connect to the speakers.
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.
