Description The Debut Aluminium Subplatter Upgrade takes all Debut turntables to the next level. The diamond cut aluminium subplatter is 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.
