Solo streamer

I would keep the purpose built streamer and add an outboard dac. Even if it’s at a later time. There’s no substitute for a good external dac unless your goal is a one box solution. 

@rvpiano I would discuss your situation and thoughts with @blisshifi who you will note posted earlier in this thread.  His experience and knowledge base is extensive.  And he seems to be more than willing to share his thoughts whether or not you are purchasing through him.      

Did someone mention the Lumin U1X or the other pure streamers?

They are excellent and used deals abound.

Also look sharp.  Sleek curved block of aluminium.

Also a very intuitive interface.

Yes, it makes sense that the N200 would sound better than the A200.
