Just had this update from NAD 
Thank you for contacting the NAD Electronics Support Crew. We sincerely apologize for the undue delay in getting back to you.
We are very pleased to announce that in the coming days, we will be launching BluOS 3.14. Amongst some other great added features, ROON has fully Certificated the Award Winning NAD M33 and NAD T778 flagship AV Receiver.
I hope this information helps and am going to mark this request as solved to prevent you from receiving reminder emails from our system.
Thank you for choosing NAD Electronics, HEART+SOUL You Can Hear.
