I have hesitated from making an explicit admission of being wrong in referencing a study about spatial hearing to back up my claim of 10us/100khz monaural time sensitivity. This is because I have (now had) been skeptical of why the brain would prove to have a 10us capability for two ears and not keep that capability when hearing with only one ear/the same way through both ears. To spare some words I also excluded pointing out the trend toward finer values that the range of microsecond-unit results take on.
"The shortest auditory click I was able to find in the literature, and which was used in a psychophysical context (i.e., audible to a human) was 10 microseconds..."
"The upper edge of human hearing is 20 kHz so it is unlikely that we could detect a difference between a 25 us impulse and a 10 us impulse (or even a 1 us impulse), but assuming sufficient energy, all would be detectable.", As in my previous post, where I talked about energy.

I think it's no coincidence that this number is the same between left/right differential and amplitude/time differential.

As delta-sigma dacs/oversampling will only ever be useful as long as high res music is not played into it. You are attributing the issue of scarcity of higher bit and sample rate material to the dac.
[...]
Either you are taking issue with PCM/digital audio in general ('staircase'), are saying that the bit/sample rate is not sufficient (quantization error), or that no reconstruction filter is in place - not that one can't be added.
Hence my use of parentheses around the words, other people call them that.
My first comment on this thread was about how the square wave test is usually excluded. I'd like to see a class d amp tested in that way.
"Broken by design" has a specific meaning. It is to state that there is something innately wrong versus there being something exteriorly wrong.
In the case of a filter-less NOS dac, you can circumvent the problems posed by circumstances exterior to the architecture before having to swap architectures.
