Time clock sync devices

Hopefully someone that has owned that combination can chime in. 

Yep, clocks are critical to digital. And as  big_greg referenced one can overdue it, the internal clocks may be sufficient, adding external or more clocks and/ or mismatched clocks may disturb sound quality.  Somewhat recently I experienced what I presume was effect of this when after adding a switch to network I suddenly noticed excessively precise imaging. Other than that one episode, better clocks have always resulted in better sound quality for me. 

You'll likely get more value passing your streaming digital through a clock than the output of a high quality transport like the CEC.  That's why many standalone clocks are network cable in & USB out

Your Transport also has their proprietary SUPERLINK connection, which allows a compatible (CEC) DAC to share its clock.

I have the Innuos Phoenix reclocker.  Yep definitely works well and Im keeping it.  You hardly ever see them up for sale used so that says something too

Clocking will have a very significant impact. The infinitesimal amount of jitter is the thing holding elite systems back.  The stepped up clock in my server was game changing and makes very DAC I have had here sound better.
