Look for examples of each on Yahoo Buyee in Japan. Best I could see is that the DK100 series uses a long armboard and is a lighter colored veneer, DK200 series uses a smaller circular arm mount and the DK300 series is like the DK100 but in a dark veneer. I'm sure there are other differences and the letter at the end might pertain to a certain species of wood used in the veneer.
Denon also built plinths with 2 and 3 arm boards just like Victor did. You need to study some old Japanese catalogs as a lot of this stuff was not offered in the States. I'm sure there must be dedicated Denon websites or blogs over there.
