As @mahler123 stated .. the devil is in the details. I use the WIFI connection and find the sound quality is superb with Tidal and my own uncompressed FLAC library. Yes, I have a pretty robust internet connection and a good router. Rarely a hiccup.
@arafiq .. it's like any other component really (i.e., you can spend $20 or $20,000 on an amp, preamp, DAC, etc.). For me, the Node 2 ticked all of the boxes when I was looking for a streamer. The Aries Mini was a close 2nd. Bluesound's broad focus is to be a whole-house hi-res solution. Their products work great alone and grouped/synced together. I also have a Pulse Flex in my bedroom and will likely purchase another at some point. Would someone else be happy with an ATV or a Chromecast Audio? Absolutely. BTW, I have 2 Apple TV's and the Node 2 is much better to my ears. FWIW, I've used the Node 2 with it's on-board DAC, my Chord Qute EX, and my Schiit Bifrost Multibit.
