Cosmos APU a notch+LNA $70 to outperform APx555b for $30000

Has anyone else seen this with ESS DAC chips?

I'm not sure I do understand the problem.
But I can state the Cosmos ADC with selected brickwall filter (Linear Phase Apodizing) is perfect in not allowing any aliases to come through (100dB attenuation).
Whatever is in the spectrum it is coming from the DUT alone.
