There seems to be a definite consensus that a dedicated streamer is preferred over the Mini connecting to a UltraRendu and then the DAC. One reason I am looking at the SonicTransporter is that it can be a Roon server. I think Audirvana can also be loaded onto it. That is not the case with Aurender and I'm not sure about Innous.
I could stretch the budget by $1000 or so. Any other suggestions for a dedicated streamer, preferably one where Roon can be loaded as a server (as opposed to just an end point) are appreciated.
