Is the MZ series higher then the WK series. I have have heard demos formt he MZ-2000 which were satisfactory. I don't know how much this KB cost ( MZ-2000), so I can't comments on its price to performance ratio. Furhter, since it has been discontinued, its older technology may have been the reason for its mediocre sounds/styles. I wonder how the WK-3700 compares?
