Hi Dave/Troy,
May I ask why the Bluesound Node 2i will not perform optimally through USB? You would be bypassing the internal DAC (which sounds decent) of the Node 2i to the better Qutest DAC. Provided you have a really good USB Cable (iFi Gemini, Audioquest or Curious) going into the Qutest I don't see why the combination would not work as well as suggested.
