Aurender N150 vs N200

Wondering which one I should do as my first streamer. I.e. how much better is the N200? I was thinking N200 at first, to just do this once, but now thinking (more responsibly), N150 would be good enough for my first.

The rest of the system:

• DAC -- Denafrips Pontus II
• Pre -- ARC Ref 5se
• Amp -- Art Audio Px-25
• Speakers -- Blumenhofer Genuin FS2
