Bluesound Node2 with outboard DAC


Has anyone used the Bluesound Node or Vault for music streaming connected to a good outboard DAC and respond to how good the combo sounds. I see the Bluesound has great connectivity and streaming options with a good user interface. Curious if using with a good dac is worth the money. 
I'm using Ayre 5xeMP preamp,  Mark Levinson 532h amp and Revel Performa floorstanders. Cardas interconnects.  
Currently using OPPO 105d as my music player and streamer,  don't like it disconnects from my tablet app control a lot and hoping for better resolution. I use Tidal HiFi for streaming and usb hard drive for stored music files. 
Appreciate relevant replies. Thanks Audiogon group

For Roon I use a Mac Mini, ultraRendu with UpTone linear power supply, and Ayre Codex DAC with balanced analog to an Ayre A7e integrated that drives KEF LS50s.  I use an iPad for control.  Could I just run a Node 2i to the Codex DAC and expect the same quality audio?

@dbphd ,
That is what I am doing.
Node to Codex. I have no experience with Roon/Mac, so I can't say it will sound 'better', but I am very happy with my current combo.

I have a differenct but related question: when I hookup my external DAC to the Node2i, do I have the interconnects go from my DAC to the amp or from the Node2i to the amp?  (there is a toslink from the Node to the DAC in both cases)
@garthb309 your interconnects need to go from the tac to the pre/amp. If you hook the RCA interconnects to the Node then you are using the Node's DAC.

2nd or 3rd the RME and I also have a node 2. Obvious improvement and only on 3rd day but was a demo so probably broken in. Excited to mess with settings as there are loads of them.
