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


I have a Marantz 8805 and use the Bluesound Node 2i to enjoy my music on. 
I’ve listened to the Node with both optical and rca and actually prefer the node using the RCA connection. 
I’ve never tried a digital coax cable.

Which cable would you choose?

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. 
Try the silnote digital coax. Extremely well built (US) and sounds beautiful. It’s on sale right now for their 10th anniversary. Great deal!
