Digital clock - any recommendations?

The fact that the clock is external and thus needs a relatively long cable to connect is defeats any benefit in the increased accuracy. Even if the clock is better, the internal clock of the Marantz using a very short cable will be much better.

Also, I would wager that <10% of producers and musicians don’t even know what DSD is; so it is very inaccurate to state the majority favors it.

Length of BNC connection vs accuracy of original clock and problems with electrical environment herein -- that's what we call a trade-off, and that's why selection of the BNC cable matters. Of course in your black and white 44.1/16 = perfect world you don't care

As to musicians and producers -- well I guess on an audiophile discussion board we perhaps care more about those who do know what DSD is -- did you look up the Cookie Marenco link I posted? Those are the sorts of people we should be taking advice from ...

@folkfreak

If you think a multi-thousand dollar CD player has such issues, you’d be mistaken (or the product is garbage).

Repeating the test with the Marantz’s word-clock input locked to a high-quality external source (a dCS 972 digital/digital converter) at either 44.1kHz or 88.2kHz increased the measured jitter slightly, to 271ps p–p, but with an almost identical-looking spectrum, including the rise in the noise floor to either side of the central peak. I couldn’t find any other measured differences resulting from externally clocking the player, but it could be that the dCS clock offers pretty much the same degree of stability as the Marantz’s own.

So yeah, like I said, there is no benefit to externally clocking any decent player; it helps in studios because it’s a multi-component chain and they want to be in-sync, a totally different thing.

Hmmm, one test with a 20 year old upsampler (not a dedicated clock) proves what? Odd how dCS themselves still promote external clocking in all their ranges, I guess all of their DACs are “garbage”, mine certainly is 🤪

External clocking is tricky stuff. For instance clocking at multiples of the base rate (eg 88.2, 166.4) often sounds worse even when you’re sampling at these rates. Per John Quick the issue seems to be transmitting these higher rate signals via BNC. Best to stick with 44.1/48 even if your clock supports higher rates imho at least

Anyway, @tzh21y have you had a chance to try one of the suggestions yet? Would be great to hear back what you found when you have a chance

I will let you know.
