Here are the FR plots (10 - 22,050 Hz source signal) for three DACs. The cheapest is usefully less than $100, the most expensive several multiples of that. One is a scarcely available little thing, another is - at least in some circles - vaunted as the bestest-most-perfectest-cannot-be-questioned-DAC-ever and "worthy" of being lauded over units costing >10x it's own asking price. The vertical axis is zoomed ... total range is 0.6 dB, so it'll exaggerate the plot vs. the "much more convenient for one particular narrative" view covering 5-10 dB (where everything will look almost perfectly flat and is about as much use as a chocolate teapot) ... yes there is a reasonable middle-ground. The little bump at ~23 Hz is an ADC artifact. Undisclosed, audio-related, "prizes" for correctly identifying: Which products are represented - and specifically which corresponds to a specific plot. Other products/lines that exhibit the same signatures. Why little Donny Osmond has so many teeth. And finally, NONE of the devices involved are from Schiit.
