Can't wait, finally we can experience the "velvet" AKM sound without breaking the bank with expensive DACs.WiiM will announce the ProPlus soon and Roon Readiness will be delivered via an OTA update after that, hopefully in a matter of weeks.
The last time I checked, even those AKM "hats" for RiP boards are more expensive than Pro+ itself but without all the convenience and features of Pro+, so I think the Pro+ will be another winner by Wiim!
