Roon > Metrum Ambre > Metrum Onyx here using I2S connection. I think it sounds great. I wouldn't think of using Bluesound with Onyx- get the baby Ambre instead.
Also R2R DAC aka Onyx can play MQA- just maybe not the "full" unfold, but as long as you get the first unfold (that is the most important) still sounds great. Once you get to the higher end DACS, the whole "full unfold" with MQA is a bit irrelevant as long as you get the first unfold.
