Thanks!
Let me be a little more specific- I want to use a mac mini to host all of the software- amazon music, blackhole, sound source, and hq player. I will control everything with screen sharing from another mac. I want to use the mac mini into my 8 channel Oktodac8. I would like to get this working with just two channel to begin with, then add 2 more channels for a pair of subs, crossovers for the subs, and ultimately, room correction and eq. I don't think I need a raspberry or any separate streamer.
Thanks again for your input...
