I've used a Bluesound Node 130 for several years with a system that some here would say deserves a much more expensive streamer. I did add an external power supply and use an external DAC, and it sounds very good. The BluOS app is one of the better ones, and that is an important consideration in choosing a streamer.
You might find the internal DAC on the 130 or later Nodes quite acceptable. I thought it was comparable to a Denafrips Ares II DAC, which many have raved about.
