The real question is do you like the sound better after adding the external DAC? In my case, I preferred the Node 2i played by itself without the DAC. The DAC made things sound thinner. Probably has something to do with the quality of the DAC. I also can hear a slight sound difference when playing MQA. Could be the Emperors New Cloths phenomenon. Wonder if anyone in this group notices a better sound stage when unfolding MQA entirely? Be curious what you hear using the Qutest that you don't hear playing the Node 2i by itself. So much to learn. So much to spend to hear 1% to 2% more. Only thing I need is more money and a wife that will allow me to continue to spend more money. So far the biggest sound difference was adding a pair of REL S2 SHO subwoofers. Once dialing them in, the sound stages becomes so much bigger.
