RPI4 Multichannel Endpoint? Anyone try this?

Continuing the discussion from Multichannel Endpoint - Still Tryin':

I’m in the same boat. I contacted suptronics and was told a RPi 4 version of this was coming in April. I’ll wait to try that as a multichannel Roon ready endpoint. Has anyone tried the RPi3 version here —> X6000 7.1CH Hi Fi Audio Channel Expansion Board for Raspberry Pi 3 Model B / 2B /B+|raspberry expansion board|raspberry pi expansion boardpi board - AliExpress
