DEQ2496 - Jitter issue


Dear all,
I am using a DEQ2496 and I would like to better understand jitter issues. This device is equipped with an auto-sync function which should auto synchronize the DEQ2496 with, e.g the digital source through the ESB/EBU input. Let's imagine that I have enough money :) to buy an Apogee Big Ben that I would fit between my CD drive and the DEQ2496. I suppose that my DEQ would be synchronized with the big ben on a very stable and accurate frequency, the jitter should be minimised and the internal clock quality (quartz) of the Behringer not an issue. Am I wrong?
Could this noticeably improve the sound quality or is the direct ESB/EBU connection between a good CD drive and the DEQ good enough (The DEQ being synchronized with the drive clock)?

There's a ton of discussion about jitter here an on other audio sites. Do some reading and you will find that it is a controversial topic. After doing quite a bit of reading myself, it is my opinion that the levels of jitter in modern digital gear are largely inaudible and that trying to correct already nominal levels of jitter with devices such as you describe are largely ineffective and/or inaudible as well. Just my two cents, YMMW, etc.
I'd suggest to get something like a Benchmark DAC1 on lone froma guitar or music store and experiment. There are so many variables that it is hard to say whether you have jitter or not. For sure it could be a problem depending on your gear, connection, power etc. Jitter is audible but in most decent modern gear there will not be a "night and day" difference - subtle differences in teh treble or lower midrange more like.
Thank you very much for your contributions. I also own a Benchmark DAC 1. I have tried to connect it behind the DEQ2496, in order to take care of the digital output. Surprinsiggly, I found that the DAC 1 was not sounding as good as the analog output of the DEQ. I need to find a good AES cable to redo this test (I was using an optical output).
My question is related to the benefit, or not, to upgrade the internal clock of the DEQ...
