For some reason I can't post to VE, and they have a good thread I found on opinions of the "best" Denon TTs, but there is no description of the differences between the servo-tonearm models; in my case, I'm wondering about the differences between the TTs with the "search" feature, meaning you can manually move the tonearm left/right. I think these are the DP-37F, -42F, -45F, -47F, and -52F. Aside from styling differences (the -47F has a BIG, Cadillac-looking presence), what ARE the differences? All have the Dynamic Servo tonearm....maybe drive motors? Plinth design/material?
