Is Roon downsampling my DSD256 files? I have an EMM Labs Dac2 which is fully capable of playing the 256k DSD, but it doesn’t have a readout so, I’m not sure what is going on.
If it is downsampling, how can I remedy the situation?
To do DSD256 DOP on MacOS you need a DAC capable of doing PCM 768. If your DAC isn’t capable of doing PCM 768 you will only be able to achieve DSD256 direct via Windows and the vendor supplied drivers.
The other way to do this is to stream to a network device running Linux or similar (like microRendu) which does not need to use DoP - I stream from Roon (running on a Mac Mini) to microRendu (via WiFi, then Ethernet) to iFi xDSD at DSD512.
