best SQ improvement DAC under $1000 to pair with Bluesound Node 2i

I found myself streaming more often than analog. Although, I will listen to vinyl occasionally, Streaming has great benefits. I have a Node 2i for 6 months now. Want to improve SQ as closest to analog as possible. Unfortunately, my budget tops at $1000. I would like to ask audiophiles who have the Node 2i which DAC  has given you the best improvement over the Node 2i.
