"This upgrade takes your X1 or X2 to the next level. The diamond cut aluminium sub-platter can be machined to much improved and higher tolerances and will be a substantial upgrade to regular sub-platters. It adds more mass to the entire platter and drive system, resulting in additional damping of noise and unwanted resonances. The improved tolerances during production will increase overall speed accuracy. The additional mass improves short term speed stability, or also called Wow & Flutter." - Pro-Ject
