Is it worth it? DAC question

I have a simple second system consisting of a Sugden A21, a Bluesound Node and  Tekton Lore speakers. I have a spare Ifi Zen DAC V2 that I used about a year ago when I used my MacBook. Is it worth it to try and connect the Ifi as an external DAC or is the Node better as is? If I did try it, how do I connect the Node to the Ifi?
