I have the older RME ADI-2 DAC (AK4490 vs AK4493) connected to both the Node 2i and the LUMIN U1 Mini. Node 2i uses coax into the DAC; U1mini uses USB.
I love them both. I think the LUMIN app is better than the BluOS app and I like the OpenHome implementation of UPnP/DLNA that is uses. But I also use the Node 2i because it supports many more streaming services.
IMHO I do believe the LUMIN sounds better (but it’s not a huge difference), so I use the U1mini for all my TIDAL and Qobuz streaming. I don’t have a Roon core and therefore don’t use Roon (I don’t have a local library of ripped CDs or downloaded digital purchases so I don’t see the value in Roon).
FWIW, I don’t think the U1mini is an upgrade as much as a nice side-grade to get a great app and excellent support. Upgrades to DAC, amp, speakers/headphones would yield more significant improvements.
