The function of the plinth is simple. It has to resist/absorb vibration, both airborne and from the ground and from within(for turntable with stand alone motor then the vibration is from the bearing only).
And common sense tell us the heavier and denser the plinth, the better. Also avoid any turntable with an empty cravity inside the plinth!
I used all of the above points to design my DIYer turntable's plinth. The plinth that I have is about 55lbs total with about 18lbs of sand and 2lbs of lead shot filled fully inside the cravity of the plinth. I use lead shot because of its high density. And sand is a very good medium to absorb/turn mini vibration(vibration from bearing, air or ground) to friction and then become harmless heat.
It takes high mass/density to combat vibration both from the air and from the ground and lead/sand to destroy them.
As for Twl, may be you should built yourself a bigger, denser and heavier plinth with sand/lead shot mixture filling the cravity. It will for sure have better performance than the stock Teres plinth.
