The harmonic distortion and IMD is low in mid and high frequencies.See the 19kHz + 20kHz IMD measurement (Pierre Verany CD track 51). The 1kHz ( 20 - 19 = 1) distortion component is below the noise level of the Behringer A/D converter. Such a low distortion is expected in the frequency range 0Hz - 20kHz from PCM1792, OPA627, and OPA604. (Ignore the spikes below 300Hz in the graph. They are noise on the A/D side.)
The roll off at 20Hz (ref. 500Hz) into about 9kOhm load is approximately 0.4 dB.
Anyway, I think the manufacturer should be able to say whether the high harmonic distortion at low frequencies is within their spec or not. They refuse to say anything like that.
