Esoteric X-03SE v. UX-3Pi

Has anyone compared these on plain old Redbook CD's? any thoughts/comments would be appreciated.

This question is also very interesting for me. How does the sound of the Esoteric Audio Video players compare to their Audio only counterparts? I know for expample that the X-03SE is supposed to have a better clock than the UX-03SE, but has anyone actually compared what the sonic difference is between the two with Redbook CD's?

Thank you
