hgeifman - a couple things. Your description can also be said about Roon and Pure Music which I’ve used for many years.
Audirvana gui sucks to put it bluntly. Audirvana might sound a little bit bit better today but Roon might make a change and it’s sound quality might leap frog Audirvana’s. If Audirvana will ever get their gui close to Roons capabilities, Roons is light years ahead right now, I still wouldn’t be able to switch to audirvana for these reasons: I use Roon endpoints all over the house, use ARC daily in my cars, and my metadata is exactly how I want it.
