I think dedicated streamers are an outdated concept that is about to go the way of the Dodo. You are locked into the apps that are available for the various services that you are interested in (as with so-called ’smart’ tv’s). I think they are the audio equivalent of the old dedicated word processors, before the advent of universal PC’s with packages like first Wordstar and then Wordperfect or Word.
In my view one is now better off with something more universal like a Chromecast Audio. No streaming service can afford to ignore its market prominence, and hence there is an app for everything. With Buble UPnP it can access a NAS. Since you can use a big screen tablet as a remote controll, navigating your library should be quite transparent, depending, of course, on your NAS software (about which I know nothing - I only stream from internet).
The inbuilt DAC is pretty decent for secundary systems (up to 24/96), but there is also an optical digital output for more ambitious applications. That digital output is bitperfect, so the final sound quality would depend on the DAC of your choice, from cheap and cheerful all the way up to something like a Benchmark DAC3, or, if you also require a disc player, something like an Oppo 205 with its optical input. The Chromecast also does multiroom.
