Hello I’m playing Roon on the following system, HiBy R6 -> iFi iDSD Black Label Micro
May I know the best setting for this?
I understand that the HiBy R6 is an MQA decoder, and the iFi is an MQA renderer. What is the MQA setting I should use in my Roon software? If you have more details on what setting I could use to make my music experience better, please let me know. 
My transducer is the HiFiman Sundara.
Hope to hear from you soon, Kai.
