Those curves for the Lokius are indeed on the Schiit website. Got to the Lokius page, click “specs”, and, at the bottom of that page click “APx Report for Lokius”. Scroll WAAAY down. Bingo!
BTW That darn LED lit up my room 😖. So, using a paper hole punch, I punched out a quarter inch circle from an adhesive mailing label and stuck it over the LED. Cuts the brightness significantly, but not so much as to make the light invisible. A gentle blue glow if you will.
BTW#2 Ghosthouse’s review is spot on in all respects. I do live recording and the EQ sounds far better than any digital work station. FYI my system is a Luxman L-590 AxII and Sonus Faber Maxima Amators.
