I bought the Element S for the purpose of using it with i2s specifically through Roon. It's been 5 months since its release and Matrix Audio is struggling to get the Element S Roon Ready certified.
MA has been awful in communicating updates about the issues keeping the Element S from being certified. In mid-August, MA said they were working with Roon to work out "one small bug". Since then MA has not responded to multiple requests for updates. Obviously, the problem involves more than one small bug; otherwise MA is very inept.
It's a real shame how MA has chosen to deal with the situation. Frankly, I suspect there are multiple issues with the Element S and I have doubts it will be as Roon Ready by Roon any time soon. MA has lost my trust and my business. There are plenty of alternative streamer options in this price range, and I will look elsewhere.
