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?

Yes, "a good oscillator (clock) is a good start". Without a good start, you have nowhere good to go. So what is this argument about?

The issue is implying that only a good oscillator is required. That's what the argument is about.  It purveys the wrong impression.

This is like saying that only a good D/A chip is required and you have the perfect DAC.  Not by a long shot.

Like most things, the devil is in the details.

The issue posed by the OP was about a better clock.  So my response was about clocks.

At the current state of the art, a femtoclock, while not a sufficient condition is IMO a necessary condition to the best possible SQ.

Also, generally speaking, if a maker implements a femtoclock, chances are the rest of the unit compliments it.  In other words, it's a good sign of quality . . . generally.  If Steve N. wants to provide exceptions that he knows of, I'm all ears.
Thanks, everyone, for your inputs.  Unfortunately, much of what was said went over my head.  Could someone recommend a good, readable reference on dacs?

Here's an article that touches om the subject even though ge talks more about usb inputs. He also has a list of components he recomends, including dacs.

I suspect a lot of new dacs sound better than your Cambridge but it doesn't have to do with just jitter.
