One quirk about the MIL (MIL Funny.. abbreviation btw) is that there are significant artifacts below 20khz under the 18kHz or 17.5kHz stimulus which are at least partially hurting the SINAD under 20kHz, so yes it is in line with Amir's and others measurements. Schiit reports conveniently (for them) don't detail this inharmonic junk. This may or may not be an issue with real life HF signal levels, someone with an analyzer needs to dig deeper into this issue to understand the impact.
