Any vibrations in the record during playback will be picked by the cartridge and will be reproduced by the amplifier and speakers causing muddy sound, distortion and reduce detail. In order to avoid record vibrations you must make certain that the contact between the record and the platter is perfect. Also many of the older manufactured records are warped. Some more, some less. This causes big problems for the diamond stylus of the cartridge to track the grooves properly. The stylus pressure fluctuates as the stylus moves up and down while trying to track the warps. With bad results: muddy sound reproduction with distortions and if the turntables drive isn’t really strong… audible flutter. In some cases the stylus may actually loose contact with the groove causing a hissing sound. Take care that the platter bearing of your turntable is able to accept the additional weight of 760 g!!! If in any doubt please consult your record player instructions or your dealer before buying or using this weight!
