Saec Japan writes. "The SRS-9 is an innovative record stabilizer that uses an unprecedented SVM (Suppress Vibration Material) mechanism. The SVM mechanism features a structure with nine separate stainless steel weights. Each weight delivers the optimal load according to the deformation of the record surface, making the entire record flat."  

"When the needle tip of the pickup scans the record groove, it is freed from the additional vibration acting on the needle tip, and it becomes possible to read the signal engraved in the record groove. This increases the S / N ratio resulting in an excellent sound. By designing the weight to 300 g or less, even turntables with weak torque can use this cartridge without hesitation, without unduly stressing the bearings."
