Hi
@Cheesefry,
I've had my NODE 2i for about a year and really like it, especially for the price. I previously had a SONOS CONNECT and the NODE 2i was a noticeable improvement in sound (UI/UX though, SONOS is still the best I've used). Even just playing Spotify, the improvement in sound was immediately noticeable. I'm primarily using Roon but the native BlueOS app is pretty good. You can even play music off of a NAS (and I think even an external drive).
The setup is about as Apple/SONOS-like as you can get, where you don't really need to think about too much (though admittedly, connecting to my NAS could've been a little easier). There was a period of time recently where it seemed like they were having some software/firmware issues where it was unstable, but that all seems to have been figured out (mine's been trouble-free for at least the past 6 months, if not longer).
For the price, I think the features and sound quality are hard to beat. I currently use Qobuz & Spotify for streaming, but I've also tried TIDAL and Amazon Music HD. If you're into TIDAL, it provides full MQA decoding.
Besides the sound quality and the overall ease of use, the flexibility is impressive. You can use it as a streamer/DAC and when you want to try a different DAC, use the NODE 2i as just a streamer. I compared the built-in NODE 2i DAC to my Topping D70 DAC and the built-in DAC of my HINT 6 and couldn't hear huge differences (though could just be the limitations of my system). I felt like the Topping had a slightly more "natural" sound, but I think it was very subtle and I probably wouldn't know in a blind test. I also think (and I think this might be in my head) that things sound a little better running through Roon (I'm not running any DSP). By better, I mean things sound a little less "digital" but it's been a while since I've compared...I just remember I slightly preferred the sound through Roon.
I'm thinking about getting a POWERNODE 2i for my office setup so that I can run speakers/headphones off of it. I'm also thinking about getting a higher-end DAC (looking at a Denfrips Pontus or the BorderPatrol DAC and using the NODE 2i as just the streamer, but I want to get new speakers first...and maybe get into tubes, haha).
Anyways, I'm really happy with mine!
Hope this helps!

BTW, the headphone amp is actually pretty good as well.
