The 99DR is a very rare drive-only version of the CD-95, with the added benefit of a toroidal transformer (adding 200g to the overall weight).
The signal board was entirely redone to hold all coaxial and TOS ICs flat instead of added vertically on the right side. No headphones circuit and output, though, but all other functions were retained behind the flap.
Meant to complement the digitally-equipped PM-95... yet more expensive than a regular CD-95 or later CD-99SE despite not having any d/a stage !
Nudies or a real 99DR here.
