One assumes Grimm have been excommunicated for having the temerity to introduce fancy interconnects.

I realise I should probably know all this stuff - but I don’t.
What (tf) does a clock do?
Similarly what is re-clocking?
The Noddy guide please.

To slightly expand on the reply from @sq225917 if it helps.The OP just wanted to understand what clocking and reclocking was. I have a clearer view now. I think.
To test this....
So do most DACs have their own clock and in fact re-clock the signals they receive?
Or do most DACs rely on the clock from the “source”.
That's more-or-less what the good ones do.Why couldn't DACs operating from SPDIF, TOSLINK or AES use a small buffer and operate asynchronously? I thought this was fairly common.
If you don't track the incoming rate, your buffer will overflow or run dry sooner or later.Why couldn't DACs operating from SPDIF, TOSLINK or AES use a small buffer and operate asynchronously? I thought this was fairly common.
An ASRC is just a way of converting clock error to data error. You still need a good PLL.Some DACs actually do operate asynchronously using an asynchronous sample rate converter (ASRC) which re-samples the incoming audio data to align it to the internal clock rather than the incoming clock.
Yep, I wrote streaming server software 20 years ago, so that's pretty straightforward.If you don't track the incoming rate, your buffer will overflow or run dry sooner or later.
