Agree. Miminal mode is all that will work.
IMHO, I have tried multiple variations and while JRiver, from an SQ standpoint, with AO in core on Win 2012R with latest Fidelizer version is my benchmark, Roon in minimal server with Fidelizer is the worst SQ on my system. I really don’t like what Fidelizer does with Roon although it works great with JRiver.
Either Roon alone on Win 2012 R2 GUI OR AO minimal server is the best I have heard ROON and quite frankly Roon alone on Win 2012 sounds almost as good as the most optimized JRiver from my perspective which is currently how I am running it. Tried Roon with Win 10, not long enough to comment.
