Cambridge CXN vs Bluesoune Node?

I'm a total n00b to streaming, and have an old-school system comprising Cambridge CXC -> Schiit Gungnir DAC -> ARC LS27 --> ARC SD135 --> Vandersteen Treo speakers.  I'm just now unboxing these after 4 years of bumpy life.  But my season tickets to the Seattle Symphony have turned into access to streaming through YouTube. So I need a way to get the YouTube audio into my ARC electronics.

I first considered the Audioengine B-Fi, and then the Bluesound Node 2i and the Cambridge CXN.  Some have told me the Cambridge has better sound, but only using its built-in DAC;  so if I use my external Schiit DAC, I wonder if i would hear the difference.

The other thing I would like to do is access Internet radio.  I'm discovering that I enjoy connecting to Accuradio on my Sonos Port when I'm working from home.  I'm actually using an Ocean Digital Internet radio as my clock radio in my bedroom.  So it would be nice to also connect Internet radio to my good system, although I'm not sure yet whether I want to pay for services like Spotify, etc.  

If you were me, with this gear and these interests, what would be the most relevant differences between these options?

Thanks in advance!
