Matt - Take a look at the DSD to PCM conversion options. There are individual entries for 1xDSD, 2xDSD and 4xDSD. This is something that has been requested multiple times for inclusion in MC. Note also the filter and gain options. SoX was a nice addition, but it does not address these issues.
For the DSD to PCM conversions in MC, you have to know that the initial conversion is by a factor of 8. Otherwise it is pure luck if you happen to get the right conversion. The number you put in >768 KHz is ignored for DSD conversion. New users get tripped up on this regularly. The options like Roon uses would be much more user friendly.
