Before we can devise a test, we need to determine what they have actually done beyond techno-marketing terms they use. I once spent a few hours looking and all I found were some vague words and nothing else. If someone has the actual technical explanation of what they say they have done, I love to see it and we can go from there.What I wonder about regarding the multibit and their claims of "time and frequency optimized closed form digital filter" is the time-domain optimization. This seems somewhat akin to what Chord claim from their approach to using FPGA and putting in tens of thousands of taps. How can this be measured? I guess not using FFT, since that only shows frequency reproduction, noise, and jitter/distortion. Somehow you'd have to measure the timing of an impulse response, and how that compared across different DACs
On Chord, we can actually measure what they have done using much more sensitive instrumentation to see the response of the filter since they mostly talk about number of taps in FIR filters. That level of detail simply does not exist with respect to Schiit's filtering.
