Hi! It looks like you got an early peek
Good news! WiiM Pro Plus has been officially certified, and we'll make our official announcement tomorrow. We'll start releasing the update in batches starting tomorrow and through the weekend.
Note: WiiM Pro Plus and WiiM Pro will both have the Roon Ready and Roon Tested badges on the Roon website.
Here's the reasoning from Roon:
Roon Ready certification means that the device is using RAAT (Roon Advanced Audio Transport) as its streaming protocol. RAAT is the way music gets from the Roon Server (Nucleus, PC, etc.) to the endpoint (WiiM Pro).
Roon Tested devices receive music in Roon via Airplay, Chromecast, and/or USB, instead of RAAT.
A device usually has both Roon Ready and Tested certification which allows users to have more flexibility overall, and especially when grouping devices.
