Snap! Today I was just reading Carlo Rovelli's book "The Order of Time" and on p83 he says the quanta of time, or Planck time, is "around" 10 to the -44 seconds... He quotes papers back to 1997 for this, e.g, https://arxiv.org/abs/quant-ph/9609002. 11 orders of magnitude difference in the reported results is a pretty big difference!
Interestingly he says the quanta of space, or Planck length is "around" 10 to the -33 cm (on p86).
[I'm tempted to ask now if this means digital will never sound as warm as vinyl, but I fear someone might actually take such a statement seriously! ]
It's rather the opposite. The shocking news for analog afficionados is that vinyl, actually all analog sources are inherently digital (sampled in time, discrete volume).

Microtonal music will evolve into plancktonal music. Music reviewers will switch to praising the skillful wobble in some soprano's voices. High-end audiophile cables will protect the signal from interference by quantum gravity waves. We are going to need smaller ears. Some audiophiles will prefer the MQA version with its final quantum disentanglement, because they can clearly tell the difference just by listening.
So we are each always dancing the robot, no matter what style of dance we pick or whether we are dancing or not. A journey of a thousand minutes begins with a 10^-33 second step. So does the journey of a lifetime. The age of the universe is even more impressive when put in terms of the Planck scale of time. Quantum space and time resolve Zeno's Paradox without recourse to calculus of infinitesimals and infinite processes.
We now know the clock speed of the computer that the universe simulation is running on. Did they also determine jitter? Maybe the clock can be upgraded for better phase noise performance? It feels very jittery to me lately.

That's because our brains (and thus our perception) are quantum-based, while all measuring equipment and computers are mechanical / classical Turing based.
It is not because we cannot "observe" time periods shorter than 10^-33 seconds that time "is" a succession of 10^-33 seconds time periods.
Like it is not because we can't find anything smaller than quarks that they "are" the ultimate elements.
Now we just need to "invent" a quantum PLL that phase-locks onto real time, providing a true zero-jitter time reference. It will lift veils you couldn't even imagine before hearing it.
Bob Carver would then show he could do it with off the shelf components at 1/10th the clock rate and achieve a sound that is indistinguishable from the original.
This would form the basis of is PTF (Plank Transfer Function) equipment series.
