If you're not satisfied with the Node 2i, you can make it sound better with an external DAC. I went down that route, trying it with a Mytek Liberty and an Auralic Vega. Better, but still not that great.
For me, replacing it was a better and more sensible choice than trying to band-aid it with power cords, ethernet cables, or an external DAC. I chose a TEAC NT-505 which was much better sounding than the Node / Auralic Vega combo (the Vega cost more than the NT-505). I'd also look at the Lumin streamers.
The NT-505 must be at or near end of life, TEAC was blowing them out on Walmart for about $1200 ($2000 originally). You should be able to find one for not much more than your budget.
Save a little more money than your current budget and flip the Node 2i if you're not happy with it.
