I've got a Bluesound Node 2i from almost 2 years ago and immediately thought its DAC didn't cut it, so I bought a Bifrost 2 and it's a significant improvement (my other DAC is a trusty 2nd generation DacMagic with a no longer available bespoke large transformer power supply and it covers a couple other sources, a "touch streamer" used for occasional background music and a CD player). The Bifrost is for high res streaming...Just installed the "64 bit" update card in the Bifrost and now I can't imagine a better sounding DAC...just elevates the whole thing.
