I have owned both the Aurender N100, and the Innuos Zen Mini.
I ended up with the Innuos because it allows me to integrate 2 systems, whereas the Aurender does not.
Both are very good units. If you don't need to add other systems, and don't mind being locked into either Qobuz or Tidal, then the Aurender makes sense.
For me, I like to have more options. The Innuos allows you to use Roon- which I find to be quite a nice piece of software. And, though I hate to pay for more stuff, I really think it does a remarkable job of doing a lot of things in an easy to use package.
If you want a streamer with a lot of options, the Bluesound Node is probably the best one out there. Though I would get a nice DAC. Well, I would get as good a DAC, as possible for any of the choices I have given.
