You don't understand the design philosophies of what Rega and other low mass companies are trying to do.
There are really two major philosophies
High mass with the thinking that the additional mass is harder to get to resonate, however, the energy is slowly released adding coloration.
vs
Low mass wth the concept that the lighter weight materials will flex to absorb energy or bounce the enegy off of the table by virtue of the materials propensity not to be vibrated by certain frequencies, and disapate that energy faster leading to a faster less colored more nimble sound.
Personaly the best table I have ever heard did battle with a $40k high mass table and sounded nearly identical for 1/5 the money.
That table used a plinth of rubber laminates to absorb all energy presented to the table and turn it into heat rather than trying to deflect it low mass or absorb it or not be excited high mass designs, best table I have ever heard $7k beats most $25k tables.
Over the last 40 years I have worked with Sota, Linn, Vpi, Kronos, Rega, Linn, Thorns, SME, and many others.
