I Herbie-ized my heavily modded VPI HW-19 Turntable to death, and it was a wise move.
Grungebuster Dots, Washers, and Tenderfeet under the SAMA Motor, replacing the wimpy stock tiny rubber feet, Tall Firm Tenderfeet under the Plinth, with 44mm Grungebuster Discs, replacing the stock Sorbothane Suspension pucks, Grungebusters under the AudioPoint Cone Feet Coupling Discs, and new Herbies Brass Coupling Discs with DB Neuralizers under the SRA Iso Base's Spiked Feet. And some others (washers and discs) were used elsewhere here and there on the SAMA Drive Motor, the Pulley Cover, etc.
These mods brought a much better neutrality to the Table that wasn't there before. it helped bring out the best of the Table, the Tonearm, and a ZYX Airy 3X SB MC Cartridge.
It seemed that coloration was lessened, Many micro-vibrations and haze were lessened, that a $600 SRA Iso V-3.0 Base couldn't do by itself.
Those Herbie mods I feel have taken the Table to about as far as it could ever go for what it is.
