The JB920, JB930 and JB980 are similar to the JB940, but the JB930 and the JB920 do not have MDLP and the JB920 uses ATRAC 4.5 instead of the newer Type-R. If you do not care for analogue output quality, you might be satisfied with the JE520 (no MDLP, ATRAC 4.5, no PS/2 input) JE530 (no MDLP, no PS/2 input), JE640, JE770 or JE780; they do not have as good DACs as the JB9xx decks, but they have an optical out.
