I see no need for that with a N200. That machine already goes to great lengths to give you a pure USB output and Coax out.
I use a DH Labs Mirage USB on my N200 as it isolates the data from the power in the cable.
Schiit Eitr/Intona Isolator and Aurender N200
I'm always tweaking my system. My wife says it's borderline OCD :-)
Will I derive any sonic upgrades using either a Schiit Eitr or Intona USB 2.0 High-Speed Isolator in an Aurender N200 and ARC REF CD6SE DAC/CD player?
Thanks!
