Digital Coax, optical, or RCA for use with my Bluesound Node player?

Bluesound did replace my unit with a new one and a new one I mean a Node 2I even though I had a Node 2. 
I haven’t received the cable yet so can’t comment. 
I already have a Audioquest power cable on it. 

For digital audio applications, coax (RCA) is generally considered superior to optical (Toslink). Blue Jeans Cable offers some at very reasonable prices.

I just received a Cambridge Audio CVC v2 due to my ARC CD player, used as a transport, crapped out (yes I tried to have it fixed to no avail).

So, I'm interested in a new RCA-RCA digital cable to connect to a Bryston BDA-3.14.  
Seems I'm hearing (no pun) good things about Analysis Plus. 
I'm leaning towards the "Digital Crystal" but would like the OPs thoughts
on the  Audioquest Carbon digital coax when you receive it. Thanks.

That would be a Cambridge CXV.

I’ve read that the nodes dac will support mqa (tidal), so I’d stick with the rca connections if you’re listening to mqa tracks.
