How can I tell if I need a better clock for my DAC?


I was interested in the responses to a related post by leemaze this week, saying that a Synchro Mesh was a good way to improve a DAC with subpar jitter.  I have a Cambridge CXU, with an inboard DAC; how could I determine how much jitter it has?

@gdhal, so if you agree with my analogy then you would have to agree that reducing jitter, no matter how that is done, like reducing stress, that is a good thing.

Yes, I do agree that reducing jitter - no matter how - is a good thing. 
Just wondering while we are talking about it, I still have an Audio Alchemy DTI, which I used between a Magnavox CD650 player used as a transport and a PS Audio Digital Link gen ll dac and it definitely made an improvement in that set up. Would that be a viable option or am I reaching?

The Audio Alchemy DTI and DTI pro both use two or more CS8412 S/PDIF receiver as a PLL to reduce jitter.  The Pro is a lot better.   It will reduce jitter, but not like a good resampler such as the Synchro-Mesh.  Worth a try though.

A clock is such a small part of the big picture . I have found 
if you have a external power supply this is vastly more profound an upgrade. The  Mojo  Illuminati -2 external power supplies are miles ahead of what are stuffed in the stock boxes.
i have a Lumin dac- D-1 Player  that comes with a crappy smps ,
evrn a Sbooster Linear supply is much better. The Mojo is on par 
even the Lumin flagships S-1  Power supply  at 3x the moneys .
my point is if you can improve your power supply well worth the efforts.
