I have to agree with Roffie. I bought the 218 for MQA in my C61R based system, but am disappointed with the sound when using it as an endpoint on my network compared to what I am used to. I am a big fan of the cheap Allo DigiOne HAT as endpoint instead, which I will simply send to the surround unit or the 218's SPDIF input for MQA unfolding until Roon comes around.
