Yes, previously the Wiim Mini had Roon Ready via update on the roadmap, but Wiim have since removed that when they discovered the specs for the Wiim Mini are not powerful enough to ever support it being Roon Ready.
See this forum topic: https://community.roonlabs.com/t/wiim-mini-streamer/185643/31?page=2
So I’m not buying a pro beforehand, because apparently Wiim doesn’t care making a statement and not being able to back it up afterwards…
