In my opinion the attraction of the Empire 208 is the quality of the bearing, platter (although it rings) and especially the motor. The plinth leaves much to be desired.
I’m sure Empire needed to design to a price point that would insure high sales numbers along with a decent profit and still exude a look of quality. The plinth is one logical place to do that.
The plinth is less than a quarter of an inch thick over most of its surface and for some reason there’s a large pie shaped cutout under where the platter sits. I think it’s a relatively flimsy foundation on which to build a turntable.
Damping the original plinth with various compounds will only go so far in reducing rumble and resonances, in my opinion. Rumble is particularly difficult to deal with because its energy is located at the lower end of the frequency range.
In my opinion the only real fix is to jettison the original plinth in favor of a much more solid alternative. That’s what I’m doing.
