Is this a personal question or a general question?
If a personal question, then my answer is: anything over 20KHz can safely be ignored.
If a general question, then my answer is: I don't know; I'm waiting for somebody to come up with solid, reproducible data to decide, while not holding my breath. Since the red book, nobody was able to provide a shred of peer reviewed, reproducible, convincing data about. Except for the "expert peers" with a stake in the game.
Seeing as the worst case is 2 uSec, I'd say no, especially if it is in both channels.
Is it single frequency data?
If I were building a really high end system for imaging, I'd be far more concerned with the absolute symmetry of the speakers and the listening room. Electronics would be far down the line. But after reading Lavry, I'd get a DAC that at least does the zero insertion NRZ with a four pole filter. I'd see no reason to go past that. Well, maybe a 96, but no further.
Unless of course I hit powerball, then I wouldn't care, I'd go for show.

I decided I will no longer address your messages directly, at least until you can define what would you take as convincing proof that you are fishing in a dead pond, where you can get at best a shredded boot out of the water. That is, what would you take as a proof that ITD has nothing, zip, nada, jack **** to do with the sampling rate, as long as sampling is done simultaneously on both channels. Math, measurements? Please note that I am not volunteering for any, since I believe it would be a a futile exercise. I'm not into re-inventing the wheel.
I'll make a final exception and suggest you to take it with Lawry and debate it with him, you may also suggest improvements and clarifications. I am sure he will be delighted to have you as an interlocutor. To me (and I suppose to all here that have a clue about this topic, and have no axe to grind) what he is describing makes absolute sense and is 100% correct.

Let me guess, Richard cannot be bothered with such details, he knows better what he hears.
You want endless and pointless debates and bickering, I don't.Elvis has left the building, how convenient.
Of course hi res is better. I give you link that record cymbal sound in hi res.
But you can not hear the different from low res is your hearing ability
May be you are too old.
So you talk about respect then post an insult like that. You are clearly not here for any form of adult level discussion.
To quote that wise sage Harry Callahan...
"A good man knows his own limitations".
Your a good man.
You continue your attack dog style of posting..you apparently adore Lavry and take criticisms and concerns of him personally. So much so, that you cannot post civilly.
I again ask, and clearly you do not have the knowledge to answer..nor have you found a Google hit to rely upon.
1. Is NRZ truly linear in that summed multi frequency waveforms retain temporal relationships?
2. If half width NRZ is so much better as Lavry indicates (page 5), is 1/3rd width or 1/4 widths respectively even better? If so, it is a truly elegant way of achieving 3 and 4 times the sampling rate with respect to output filter demands.

And its threshold of audibility
Blauert, J. and Laws, P. "Group Delay Distortions in Electroacoustical Systems", Journal of the Acoustical Society of America, Volume 63, Number 5, pp. 1478-1483 (May 1978)
Frequency Threshold of Audibility
8 kHz 2 msec
4 kHz 1.5 msec
2 kHz 1 msec
1 kHz 2 msec
500 Hz 3.2 msec
Some more recent work showed that these thresholds may slightly decrease with the SPL, being always well over 1mS, anyway.

Me but that is more of some irrational belief hanging over from when I was young and stupid enough to believe magazine reviews. I have never tried changing the alignment to see how that affects things. Although now I have the tools to do it. It's on the 'one day' list.

Luckily however, that is not localization. If it were, we as a species would already be dead, as the predators woulda wiped us out.
Good paper however.
15 years, I still don't know how to pronounce his name.
