"the units are specifically desinged to complement one another, especially with respect to clock speed"
please explain......! changing the cheap crystal in the DP-90 to a much better clock has absolutely nothing to do with "clock speed"......!
i believe that putting a better clock in the DP-90 will improve this combo alot......i never heard of a player with this kind of "clock" that didn't improve alot with a new and better clock....!
comments please..... :-)
