Best streamer to replace my Mac Mini?

@audiotroy -- I was just offering info, not an opinion one way or the other. Your initial response to @brunomarcs gave the impression that you were not familiar with the situation.  His comment -- a sarcastic jab -- was perfectly clear to me in light of what had transpired.

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. 

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

The software that runs on the OS.

@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.
