Yes it will. It buffers the signal and uses it's own clock if there is any jitter it's not perceptible.

Having good jitter reduction and a good clock internally always helps. :)
Best of course is to use asynch USB so the clocks short and long term match up perfectly.
To be honest though, around 2010 or so DAC's jitter reduction seems to have improved remarkably. It's really hard to find a DAC that doesn't have absolutely excellent jitter rejection at any price.
Any jitter on S/Pdif will be suppressed. It doesn't matter what introduced this jitter (CDP or digital cable). The only jitter that cannot be removed is recorded jitter. Early digital recordings were sometimes done with poor, jittery A/D clock. Such jitter cannot be removed and the only way to fix it is to digitize again, if analog tapes are still available.

It’s unanimous! Almost unheard-of on Agon.Little too quick on the trigger there sunshine
If this were correct there would be no difference to be heard (and there is I’ve heard it https://ibb.co/YdpJMJs ) if a separate word clock cable was used to sync both transport and dac off the one "dac clock", instead of them using their own clocks.
The Benchmark DAC 3 distortion and noise level is -140db no need to worry about jitter induced distortion. This is true of competently engineered modern DACs. There are even a few R2R DACs that manage to keep distortion and noise below human audibly but I wouldn't waste money on them they're overpriced. The RME ADI 2 FS is very good DAC that's cheaper than the Benchmark.
Benchmark does not recover clock from the data. It ignores it (asynchronous rate converter). Benchmark specifies insane jitter tolerance of 12.75 UI bellow 3kHz and 1.5 UI above it. At audible frequency of 10kHz jitter tolerance would be 0.1ms * 1.5 UI = 0.15ms. That is still insane amount of jitter (0.15us typical jitter will be more likely). Benchmark defines tolerance as "With no measurable change in performance". Perhaps we can hear what is "no measurable" but we're talking 1000x difference between typical jitter and Benchmark's tolerance.
@cheeg I will hear it myself on Thursday. I bought it a few days ago and it is being shipped from China. It will need some time to burn-in.
I have a 30 day trial period with this purchase.
@cheeg No problem. My frame of reference is the AudioMirror Tubadour III SE tube DAC that is really growing on me. At the other end is the Benchmark DAC3B that is amazing on great recordings and a little strong on bad recordings. I am hoping the Gustard is just right in the middle of those 2.
I was hoping to use the CODA 07x preamp with the Gustard and RAAL SR1a but the preamp is delayed another 2 weeks. So I will be focusing the Gustard on my floor standers with Benchmark gear (HPA4 + AHB2).
Just like with anything, when you’re wondering about jitter... first get used to the sound of your system/gear as is. Then make a change and see if you hear any difference. If your DAC really does turn out to be "immune" to jitter... then changing USB cables (or whatever digital cable you’re using) should have no sonic impact. That’s an easy thing to test... just barrow a few alternate cables and swap. If you hear no difference at all, then that’s a coin in your "immune" jar. If you hear any difference at all, your DAC is not perfectly immune.
I’ll just say that I too had hoped that USB had finally found a way to defeat jitter by placing the master clock in the DAC and pulling packets etc. Well, at least with my DAC (Hegel HD30) USB cable swapping was clearly audible with a few cables I tried, and more dramatically, adding the PCT USBe in the path (between Aurender and DAC) has revolutionized the sound. A lot of marketing hype will throw out words like "immune" and perhaps your device is designed in such a way that it truly lives up to that claim. But even my Hegel DAC was supposed to be relatively unaffected by upstream jitter via USB given it’s design, and I’ve found that to be not the case at all.
p.s. I’m using the phrase "jitter" to broadly mean anything that allows the data to still arrive at the DAC uncorrupted, yet somehow the sound of D/A conversion is affected by other factors that are not digital in nature. Jitter (timing of the data) is most often discussed, but there are other non-digital variables as well such as noise. It’s entirely possible that what many of us hear and call "jitter" when changing cables and transports is really just changing the type of electrical/mechanical noise that gets sent along with the data to the DAC. Galvanic isolation is an example of a device that attempts to address this type of variable.
