One advantage of Roon is that it is hardware independent in the sense that it eliminates the use of proprietary apps for accessing content so a hardware change doesn't require having to use a different manufacturers app. That and the fact that Roon's interface is superb.
Would I benefit with Roon?
I use a Bluesound Node 2i with a power supply upgrade in my main system and a Vault 2i in my second system. The Vault has about 800 CDs and my old iTunes in it. They are both on the same LAN so I can access either and listen anywhere in my home. I stream mostly Qobuz, Amazon Music, and various streams through Tune In. I like the Bluesound App (on two computers in two locations) a lot, but find that it gets clunky and has to be rebooted from time to time.
