The Bluesound Node is a decent inexpensive starting point to try streaming, but its user interface is just one of many options so the sound quality and user experience, which are the two most important parts of a streamer, aren't necessarily going to match what you are looking for. Particularly since you said i would be sound quality that sells you on it.
I recommend looking into, and trying out before buying anything if possible, the software of various products to first figure out if there's a user experience that appeals to you. Lumin, Auralic, Roon, Bluesound, etc. all have software you can download and for some of them, parts of the UI will work even if you haven't bought anything yet.
After that, figure out what hardware works with the software you like. Personally I'm a fan of Lumin hardware and the Roon software.
I do agree with others that Qobuz would be an excellent source. Versus other services that only offer lossy sound quality. Qobuz has their own app, of course, and will work over AirPlay and Google Cast.
