Great outcome! I am glad to hear you’re loving N200 in your system. My experience jive with yours, better cabling is equally important and complementary in elevating performance of higher quality components.
Network renderer or endpoint is a good option (just like VC in a DAC) that offers convenience but they cannot compete with full blown, well executed components like a streamer or preamp.
Among other things, N200 also offers external grounding that further lowers the noise floor. Once you settle down with N200, I recommend trying passive grounding from Entreq or Acoustic Revive.
