Streamer/DAC combo or stand alone DAC with Node2?


greetings,

I am looking to complete/upgrade my hifi setup and would appreciate divergent thoughts on the topic.  

System:  McIntosh MA252 Hybrid, Spendor D7, Node 2 for Tidal.
Budget:  Anything under $3000.
Based in Belgium with a journey to the States in the summer.

I listen to Tidal 95% of the time. The Node2 is fine, but is now the weak link in my system.   I've heard the Chord DAVE and the Qutest, both good.  I found Mytek LIberty and Brooklyn + to not do much beyond the Node. Surprising.  

As I pretty much only use Tidal and will never use a computer or Roon etc., I want one more box to either improve the Node2 or replace it.  I don't want to open up the MQA debate, bit it would be nice to have a MQA capable device.

Suggestions please.

The node2i according to their marketing uses newer tricke down technology from the NAD masters 50.2 which is one of the differences between the 2 and 2i but it does use the same dac as the  node2. I have never heard the node2 but the 2i sounds great to my ears.

I was lamenting to my dealer yesterday the fact that six months later my Node 2 is replaced by the 2i.  He claims he's heard it and there is no difference.  I reckon he said it to make me feel better.  Many reviews have intimated there is an improvement in sonic quality.
I don't see how there could be sonic differences between the 2 and 2i.  They use identical DACs and the only differences are connectivity options.
as much as I would like a R2R DAC
the NAD C658 checks most of the boxes and would be way more useful for a lad of limited means such as moi
the ESS chip... is that "better" than the flagship AKM?
