The BlueSound Node 2i is like a gateway drug. It's a good way to get started, but may leave you wanting for more, especially if you really enjoy the sound of vinyl. It has a great app and is easy to use, but you may eventually find it lacking sonically. If you'd prefer to skip past all of that and have a $2K budget, start with something like the Lumin D2 or TEAC NT-505. You'll probably get some other recommendations in that price range.
Adding a DAC to the Node 2i is a band-aid that will improve the sound quality, but not as much as just buying a better unit. I added an Auralic Vega DAC ($3500 when new) to my Node 2 and while it improved the sound, that combination was easily bested by the all-in-one TEAC NT-505. The app is not as good s the BlueSound app, but you can use the Lumin or Esoteric apps or BubbleupNp or Roon to name a few, all of which are better than the TEAC HR Streaming app.
