As a computer guy, I used think much the same thing -- how hard is it to get the timing right?
When I was introduced to Ed Meitner, of EMM Labs and Meitner Audio fame, that changed, because when he explained it to me, I figured out it's not only thinking about the data in terms of 1s and 0s, but, rather, how the hardware and software has to decode a 1 or a 0 from the stream. You see, there isn't a 1 or a 0 to flash a light on -- there's a representation of it in an electrical medium and the system has to interpret that. How accurately in terms of timing that interpretation happens affects bit-to-bit jitter.
It's for these reasons that Meitner is 100% against external clocks, as are others, which I can understand -- because where the clocking matters the most is right at where the bitstream enters the DAC, so that's where you want it situated by.
But wouldn't an outboard clock separate phase-noise from sensitive electronics ?
Clock reviews, over the years, reported an improvement. Inc. one a year or so ago on Ultra Audio.
There are many issues with regards to clocks. And preferences among reviewers can vary.
With that in mind, I have not attached an external clock to any DAC I've had as I've never had an external clock that takes one. To-date, though, I'll say that the best DAC I've heard is the new DA2, from EMM Labs. Review coming in July.
