Difference among Denon turntable plinths DK100, DK100G, DK100F, DK200, and DK300?

I only can tell you that the DK300 was the plinth that came with my Denon DP80 in an ensemble that included the DA307 tonearm.  It was a single-arm plinth.  Because they paired it with the DP80, I have to assume it was top of the line for that period.
