The Classic Evo subplatter upgrades all older The Classic turntables to new The Classic Evo specifications. The diamond cut aluminium subplatter can be machined to much improved and lower tolerances and will be a substantial upgrade to regular subplatters. 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".
