Want to evangelize a bit: Lumin streamers are awesome! Bought a U2. Seriously great hardware and software. The U2 replaced a Sonore Optical Rendu Deluxe.
For reference, I run a Windows machine in a basement closet that connects to a Sonore opticalModule deluxe feeding 75’ of OM1 MM fiber with Finisar SFPs at both ends (sonore opticalModule and U2).
I use JRiver for my own, extensive, library and Roon for streaming Qobuz and Tidal (spend much more time on Roon these days). Works perfectly for both, and other systems per Lumin (minim, Audivarna, Qobuz connect, Tidal connect, etc), if I ever need it (main reason I switched to the Lumin, more flexibility).
Before installing, I had modest concerns about the U2 working with JRiver/JRemote, I shouldn’t have. I connected the U2 to my network and everything just popped up like it should. Given, I’ve been streaming for a while now so my network is configured well for streaming: multicast discovery, hard-wired connections to all key pieces, etc..
And, as everyone in this thread knows, Peter Lie is just amazing with customers that post here and elsewhere. He does his best to resolve any issues (zero for me, it wants to work correctly). Wow!!
I’ve posted this in several places now. Really impressed and want to get the word out best I can.
