That's another point you don't need to resolve frequencies in their own bins. The derivative of phase is frequency (i.e. Hilbert transform) and you can resolve frequency without the long FFT's.
Who is trying to do that? I have seen others try to restate my statements in an attempt to strawman me incorrect. (Yes, I used strawman as a verb).😀
I said at exactly 2x, the limit, the sampled stream of a sine cannot be reconstructed as a single amplitude and phase sine.
As sampling increases above 2x, the required sample size for a specific accuracy falls.

Benb: a 2khz signal riding a cone running 20 hz, the time spent at the extremes in excursion...the distance to ear exceeds ITD thresholds.
Jitter as a location variation, not Doppler as a velocity variation.

That's where the fun (and confusion) starts 😀. Two samples per period (slightly less than a period apart) are enough for the infinite sine, since the concept of phase doesn't exist (what would be the reference for phase?).
Are you one of those NOS guys? Even 2x oversampling with an analog anti-imaging filter effectively uses a lot of samples in each output instant.
Don Quichotte, meet the windmill
. Did anybody claim it can? Per #33062 that would "kinda" violate Nyquist. Like in half pregnant, mind you.

All samples at zero crossing are possible only if Fsignal = Fs/2. If Fsignal is properly limited to < Fs/2, your scenario of all samples exactly at zero crossing is impossible.
Back to DAC’s again I see.
I am sure this is what hell must be like. Caught in an interminable time warp recycling the same questions and the same answers.
I used to feel the same way during our monthly, quarterly and annual business review meetings when I worked for a large MNC.
A bunch of SVP’s grilling us unsuspecting grunts about minutia that was of no consequence and then announcing with a flourish that clearly we weren’t up to the job, before flying off to repeat the whole charade with the next business in the corporation.
This is the beauty about being an atheist. You know you will face none of this.

You clearly had an expectation management issue. Were you expecting praises from a gang of SVP fat cats? Being always unhappy with the business results is on their job description, I have never seen one otherwise *)
Rest assured they had the same feeling when the CEO did their reviews.
*) Well, in the last 25 years. Good ol' times when we were all in the same boat are long over.

That's one heck of a driver to cover that range. Now humour me. speed of sound is approx 340m/s so 5us is 1.7cm. That's a lorra xmax and I wouldn't want to use those (although the purifi drivers are getting to that range)
I just googled speed of sound in inches per microsecond.
Came up .0135 inches per microsecond.
5 uSec is about .065 inches.

Right. It could possibly matter relative to something in a physical problem being investigated. Or not.
How do you mean Mark, you/we know how signals sum but the DAC doesn't and it doesn't need to?
