2016 was the year when we got our DACs roon tested. So I guess this sign referred to the “Roon Tested” state of our DACs and of course you can use a R1000E as a DAC for any roon endpoint.
In the whole interview you mention there was not one single word about the R1000E being Roon Ready.
Anyway - today I received the confirmation from Roon that the R1000E has passed all certification tests.
We will make the Roon Ready firmware available to our customers via free of charge web-update within the next 1 or 2 weeks. I will give further notice when the firmware update becomes available.
