MQA when upsampling

[wklie (Peter Lie)]

Should I at least set it to decode, so I can get the first MQA unfold? If I set it to “no MQA capability”, it will decode, then just upsample to DSD512. I want to be able to play MQA when presented with the first unfold, so I am guessing I should just set it to decode with no rendering, which will preserve the MQA stream even when I have upsampling turned on, correct?

Preserving the MQA stream is beneficial only if you have a MQA DAC. In your case @Ratbert is correct that you should set the DAC to “No MQA Support”, such that Roon will perform MQA Core decoding then upsampling as necessary.
