""" So, I would ask for some hard facts, like what is the platter mass, what kind of motor does it use and how much torque does it generate when needed? How is the plinth made and with what materials that we might think are good for dampening? """
and what I posted was that everythink is in the link and that you have to read it again and that all the 2000 series comes with coreless kind of motor.
Yes, specs maybe don't tell us all but it's important to take in count because ( some way or the other ) is the only objective information we have because we don't have on hand the 2000. My statement is valid for any audio item, I know you don't " care " and fine with me.
The @jpjones3318 post is right regarding that in that spec Yamaha did not specify the standar below took that measure.
After that post I check in the japanese bible and that 0.005 number is stated as 0.002%! showing no standard about.
Anyway, as I posted several years ago the GT 2000 along the top Kenwood, Exclusive P3a, Sp 10mk3, Denon DP 100 and maybe the Sony PS-X9 ( I think ? ) is at the very top DD vintage japanese TTs. The JVC does not belongs to this " particular/special " group or the DP-80/75.
