Hey @Walter_Dreher,
After chatting with our internal certification team, I can confirm that the Cabasse Pearls are not yet certified with roon, and therefore cannot connect via wifi or ethernet to stream until they are certified.
Until a device is certified roon ready, the only way to use it with Roon is via a direct connection to the Core or another Remote - or with Chromecast/Airplay.
To use Airplay, you will need an iOS device to set this up (as @BlackJack mentioned.)
While the pearls are in the process of being certified, due to the intricacies of the process, I’m unable to comment on a timeline for certification.
Please let me know if you have any questions
