@saulh I am an authorized Aurender dealer and was just on another thread where the OP was contemplating between an Aurender N150 and N200. Given his current components, I provided guidance for him to start with the N150.
Given your current components, the N200 is a more fitting streamer. The N150 is a very admirable entry level streamer and a higher performer than many other competitors at its price point (Lumin, Innuos). The N200 however has a significantly better linear power supply and clocking architecture that will result in a wider, deeper and more holographic soundstage with a lower noise floor. The image will snap as well more due to its improved timing. And the best part is, you have great taste in components and speakers that are resolving enough to take advantage of the performance gains evident in the N200.
