Streamer/DAC combinations

Update:

Just placed my order for the Iris and Pontus combo.  vthokie83, how do you recommend wiring?  Alvin gave me a suggestion, but would like yours and other Pontus users input.   Many thanks to those who contributed on this thread.  It was great to have other opinions.  I'm sure others will benefit as well.

Soix, any advice on wiring. 

Improved soundstage. I feel my streaming setup may be lacking in that area.   

Thanks for the suggestions.  I've been at the Denafrips Pontus II.  Do you think the addition of that to the Node would yield good results?  Then add an upgraded streamer.  Or is the Node not going to deliver good enough data to the DAC to make an audible difference???  Again, thanks for the suggestion!!!

Thanks to everyone for all of your suggestions!   I appreciate the input.  An external DAC is the obvious way to go.  Seems like the Denafrips Pontus II is the most popular suggestion.   kmcong mentioned the PS Audio Directstream DAC Mk1.  Thoughts about that DAC  vs the Pontus?  With the pace of improvements in the last few years, is an older generation of a higher level DAC going to outperform a new generation of a less expensive one?  Keep this conversation going,  it's been great to see the different points of view.
