Moon 100d sample rate issues

I’m having issues with the quality of my set up. I’m running a Raspberry Pi B+ with HifiBerry Digi+ (standard), SimAudio Moon 100d DAC, and Jolida amp (grounded).

My DAC is reading 44.1kHz output and while most of my library is ripped from CDs and are in a lossless format. I have tried the up-sampling to be native or to turn it off completely with no success. I have read that the Moon 100d is not a supported DAC and I may have to fiddle with the set-up to make it work, but I’m not sure.

Any help is appreciated.
