Check out the reviews on Audio Science Review. Big database now. Lots of DAC and streamers measured and disected.
The bluesound is reviewed here
https://www.audiosciencereview.com/...ents-of-bluesound-node-2i-streamer.6631/Price has almost no correlation with performance you will find. In fact the pricier usually the less of a sure bet....
Anyway, the minidsp SHD was recently reviwed and also has dirac on board. If you havent tried Dirac its worth looking at.
