A better test would be a 50 Hz square wave. Basically half an impulse response that repeats over and over again. Probably the only way to properly characterize a DAC in the frequency and phase domains.
Or a series of 32 , 320, 3200, and 32000 tone tests attempting to construct a 50 Hz square wave from its precisely phase-matched Fourier components (i.e. to make the edges square up to the bandwidth of the device (say 40khz to be safe a 96k sample rates).
I bet the noise floor rises disproportionately with the number of tones. I could look up the articles and quote them just to have ppl make grunting noises in response so what's the point.
Be careful your "science" is not a semmelweis reflex: "Mob behavior found among primates and larval hominids on undeveloped planets, in which a discovery of important scientific fact is punished". (Timothy Leary).
