I find myself not understanding the OP. The Node 2 has a built in DAC. It's ok but nothing special. If the Node is connected to your pre amp by the analog connects that is the DAC that you will hear. If you connect it digitally to an an external DAC then the external DAC will be heard. Which is better? Devil is in the details. If you have a stupendous external DAC, I would respectfully suggest using it. If Said external DAC is a $39 Wal-Mart special, use the Node. When in doubt, listen yourself and see which you prefer.
Wired vs Wi Fi? The manufacturer suggests wired. That's what I use. My wi Fi set up is somewhat dodgy, thanks to the incompetent folks at AT&T.
