I’ve had a Node 2i for nearly a year. I did go through some growing pains with it, especially in trying to group it with other devices for Roon playback. Those issues seem to have been resolved. I’m coming to the conclusion that, especially for the money, this has been one of my best A/V device purchases ever. Caveat: I almost always do have it hard-wired to an Orbi WiFi satellite, so cannot speak to issues others may be experiencing with it untethered.
Its value has become more evident to me since I acquired another device (the iFi Pro iDSD) that does (or is supposed to do) many of the same things the Node does. The iFi Pro (at ~$2500) costs over 4x as much. In doing rapid A/B tests, for the life of me I hardly can detect any difference in the SQ. In almost every respect other than SQ, IMO the Node 2i out-performs the iFi Pro. The latter is not Roon-ready at all.
For about $550, what other ~Roon-ready devices do everything the Node 2i does, and do them all equally well? (Without a clunky external power supply, in a small attractive form-factor, fully remote controllable, and as part of an ecosystem of other network devices.)
