Best streamer to replace my Mac Mini?

@audiotroy - site says it runs RTLinux, so what did take 5 years of development?

I'd say check software that controls the unit first. Many streamers pretty much require Roon. I don't want to pay for sub, so I got Aurender. 

@jastralfu - yeah, I get that. Although 5 years is enough to write *a lot* of code really. However, the comment was "that the operating system alone, took five years at a considerable cost" - hence my question.

@jastralfu - yeah, i am retired SWE as well. I don't want Roon either so I went with Aurender, they have standalone app.
