Setup was painless, even easier than the Node. I have it running in on repeat for a few days, but out of the box the sound was very good. I don't want to say too much too soon, but it sounds more dimensional than the Node, or another way to say it is perhaps "less flat".
Still undecided on the Lumin control app. It's not bad, but not sure if it's as good as Bluos. After fiddling with it a little last night I was starting to get used to it, so time will tell.
