Digital clock - any recommendations?

@mzkmxcv. If you have read the manual for the SA11 S2 you’d know it has an external word clock input ...

As to the value of DSD I suggest you spend some time with sources like this, and really try to listen to a true high end digital rig one day without prejudice. In my system where I listen to all Red Book upsampled to DSDx2 I find that DSD gives a more continuous performance retaining more of the gestalt of performer in room. You’re welcome round my place if you’re ever in the PDX area and want to hear what I mean, changing the sample method and filters is easy and all the adjustments are clearly audible.

What may them blow your mind is to discover that the more esoteric, and costly, the setup the more it responds to detailed tweaks. Yes footers, power cords, damping stones and even anti vibration stickers all matter and are highly audible in a $200k digital setup ... kind of annoying, no 😉

actually, this is all new to me.  I was just very amazed at how much the clock made the transport player better.  If it is not worth doing, i want to know that also.  I was just curious as my player does have external clock connection.

It does have a clock input, but what are you syncing it too? A master clock is to make sure all the components are in-sync.

All you have is your Marantz going into whatever preamp/integrated you have. Does that have a clock input as well? If not, there is nothing to sync the Marantz too. As pointed out by the other user, the Esoteric was using the clock to sync all of its separate components together, not a common layout for the majority of setups. 
 
DSD can’t sound more accurate, because PCM is already 100% accurate (down till -95dBFs at a minimum). Now, your DAC’s filter for DSD may be more pleasant, but that’s a case-by-case basis, and has nothing to do with the actual format.

Once again our friend  @mzkmxcv gets it all wrong. While clocks can help synch multiple devices a stand alone clock can also benefit a single device - were you not paying attention when I said to look at the dCS Rossini or Puccini setups or the review of the Vivaldi one? All of these single box systems that benefit from add on clocks

And your opinions on the perfection that is Red Book PCM are at odds with the vast majority of musicians, producers and audiophiles - again please take one of us up on listening to a real high end digital setup one day.

Might I suggest you buzz off and leave the op alone if you have nothing new to add?

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.
