OP update, I ended up finding an upgrade Audio Mirror Tubadour III for a good deal and hooked that up last week. The difference between it and just running the Node 2i was substantial. The music is less "bright" and not as fatiguing and the realism improved dramatically. A very good investment and a good first step for $1,000. As I upgrade I'll look towards the Terminator but was happy to hear such a dramatic improvement in the music quality with the addition of a separate DAC.
Best,
Mike
