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.
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.
