Roon seems like a cool idea, but ultimately didn't work for me. I didn't really care about the streaming integration (I know, a big selling point). The DSP and streaming to multiple endpoints were the selling points for me. The DSP was great. The streaming was... less seamless than either Airplay or Sonos in my house. Not saying it doesn't work for people, but it didn't well enough with my setup to justify the rather steep price.
Interesting, my comparisons were LMS, Chromecast, and DLNA/UPnP, and Roon has been a huge improvement, literally no streaming issues in two homes with 4 streaming points each (Roon-Ready, ROPIee, and Chromecast).
