Good point, I also looked at REW and bought the relevant mic only to find my 818's USB port doesn't work, so I can't play the sample files through it. Meridian say they need it back, but my dealer didn't respond when I tried to book this in during my holiday, so it's going to have to wait another few months until I'm next on holiday.

My only concern is that this will break MQA as to use REW on Roon, you need Roon to do the first unfold and then get the Meridian to do the second. And, right now, this process is broken as the 818 can't understand partially unfolded MQA, so everyone's waiting for a fix.
