Amarra SQ+ output not bit perfect?

I just started an evaluation of Amarra SQ+ and am running into an issue. I have set Roon to output to Soundtream, and SQ+ to output to my Dragonfly. Audio does play, and I am able to control gain from SQ+. But, the audio quality is “high quality” in Roon rather than bit perfect. The only source along the audio path that is not bit perfect is the OS output. Have any of you ran into this? Recommended fixes?
