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

OP
I had huge issues with the OPPO app on my phone doing exactly the same and eventually gave up with it.
The OPPO is used purely for movies now and I use the Bluesound vault2 as my dedicated streamer, no connection issues from the Bluos app.
I'm also thinking of using an external DAC with node 2... and I'm also wondering if spending $1000 to $1200 going to get any tangible or even worthwhile boost in SQ.
aliskhan. 
I would have to say a resounding YES.
The weak link of the vault and node is the DAC, any half way decent DAC is an improvement. 1000 to 1200 gets you in the very good DAC market in todays equipment.
I must say that a few weeks back I bought a very lightly used Benchmark Dac2 in mint shape for $1,200 and connecting my Oppo BDP105d to it and the difference in sound is amazing. One of the best tweaks ive made, a great dac. 
Recently bought the RME ADI-2 DAC. Hooked it up to my Blue sound node and it was a huge improvement. RME is a German Pro Audio company that builds recording studio gear. It's a 32/768 kHz converter. W/features not found in other Dac's. Check it out on their website
