Trying out the roon app I’m trying out on a 2011 Mac Mini, connected directly to a Yamaha reciever. Going directly with HDMI, at least near term. I do have an external DAC I’ll probably wind up connecting, but the DAC in the Yamaha sounds fine for my old ears for the present. I know in general, HDMI is going to have more bandwidth available, but I haven’t seen any postings discussing any disadvantage in just using optical out of a mac mini for hi res audio files, as it saves me looking at a mac screen or screen saver when connecting that way (I know, 1st world problems). Any thoughts on this?
