Why would I need Roon?

I trial'd Roon and Audirvana.  No doubt Roon has an awesome GUI and some good features.  However, I never liked the sound despite moving everything over to a Raspberry Pi and tweaking all of the settings.  Audirvana just sounds good, no tweaks necessary.  

Room is a luxury. No one "needs" luxeries Many desire them. If you're comfortable in a Civic there is no "need" to pay up.

I would not consider a Room subscription - I got lifetime, and I’m old;)
All the above regarding interface, radio and SQ is correct. UPnP stuff is awkward & ugly, I rarely played music when I depended on those. Also, the truly transcendent DACs from Ayre and DCS are Roon endpoints.

Room?

Space. Yes
