i have a zenstream now, in addition to using sonore's optical rendu setup as renderers w roon... one usb out one clean spdif coax out, both are excellent
there are numerous youtube vids on the zenstream, it is a very very nice sounding unit, but some issues experienced by many (which may have been resolved now, via firmware updates) when using wifi
i myself use ethernet, the unit (while admittedly looking a little like a martian toy) works very well, sounds very pure
i still have my trusty nodes (2i and 3) but they are relegated to back up duty, will move to other lesser applications as endpoints as occasion arises
