<< Just because the clock originates at the DAC (which is the best topology IMO) doesn't mean that all incoming jitter is eliminated. >>But, according to conventional engineering practice, it is!
There is always a FIFO (of at least one bit) on the DAC side of things. Since the data coming out of the FIFO is reclocked by the clock in the DAC box, please give us a plausible mechanism whereby the jitter from the transport can make it through the FIFO.
The same exact situation exists inside one-box players. But here there is a plausible explanation whereby the shared power supplies between the transport and the DAC sections provide a plausible mechanism for the jitter to be transferred to the DAC. But in a two-box player (especially one with a fiber optic data connection), any explanations are tenuous at best.
