I am sure this was a typo, but the N200 sounds notably better than the N100 or N150. The N2x are the current versions of Aurrender streamers. If you can afford it, I would recommend the N200. You will get years of outstanding sound quality.
The most important high quality streaming services are Qobuz and Tidal, Qobuz sounds the best by a small margin but offers 500,000 high resolution albums in addition to millions of redbook CD quality. Every streamer I have ever seen supports both of these services.
