I haven't been following all the developments of Roon but I have an MD600 and remember that the reason I didn't adopt Roon was because initially at least the library had to be migrated and reformatted or dumped onto a QNAP to work properly with Roon. Is that still the case or is it easier now for Roon to see a Sooloos library on an MD600 and use it? I have 818v3 as one endpoint and also 861v8 as another.

Studio System: UltraDAC, Analog Speakers, QNAP IS-453S Pro
Theater: Trinnov, 8kSPE, 4 5.2kSE, 7.2HCSE, Analog subs, DSP8000SEs
