I guess we can add platter mat like gunmetal Micro Seiki CU180 or CU-500 on the platter to change the weight, also a record weight like Micro ST-10 on top. Then we can compare the sound with ot without mats/weight. It's not necessary to change the platter itself.
Those Micro Seiki accessories are not for every turntable, but many turntables can accept them.
