Experience with Bluesound Node 2 use with external DAC


I am very impressed with the Node 2.  So far my use of the Node has been with it's built in DAC.  It sounds great.  Since I don't own an outboard DAC I have had no other choice but to use the Node's DAC.  It is hard to fault it's DAC at any price much less the $500 price of the Node.  That being said, I realize there are alternatives out there than can improve upon the built in DAC.  I am at a point now where I am curious to hear what an external DAC may have to offer in terms of sound quality.  For those of you who are running a Node through an external DAC, what would you recommend and what type of improvement have you experienced vs DAC in the Node.

Running Tidal MQA music is surprisingly clear, coherent, and made a huge leap (for me) in musical enjoyment on the BS Node 2. It took me a long time to match album .jpg artwork with albums songs in folders for me to access my local drive of music. But that music does not sound better than the MQA stream from Tidal. I just hope they keep adding more and more album titles.....
Has anyone on this thread or otherwise had an opportunity to compare the overall sound quality (DAC and analog stage) of the Node 2 to the Oppo UDP-205? If so, what are your impressions?
Sorry to revive an old thread, but can anyone with a Node 2 tell me if it supports gapless playback?  The Oppo Sonica's lack of gapless playback for file streaming is a deal killer for me.  It just drives me bonkers when there is an audible gap.
