+1 regarding the Denafrips dacs but there is something else you may want to consider...You have a golden oppurtunity right now to hit two cans with one rock. Seriously consider a decent streamer dac combo the Node is an ok streamer (in its day) but you can do much better with what is on offer now. I respect your concern about Chinese goods but truth is inside everything being discussed likely has parts from China; thats just the facts.The Cutest is a great little dac but is overpriced especially new.
The Node is likely a bottleneck also not just your MM2 if you stream often,I would suggest a Eversolo Master Edition DMP A6 streamer dac,small form factor and is far and away better than the Node. You are getting very good suggestions here but I don’t believe you need to go to your budget ceiling to achieve a vast improvement in your system. As others have suggested buy on Amazon if you don’t like it return it.
