Material: Base made of graphite of high purity (99.99%) + Ball made of special ceramics
Review: It can obviously improve details, gradation and analysis of music so as to inflect sound of piano, guitar or violin more sparkling and crystal-clear, voice more fruity and soft. High-frequency (HF) and medium-frequency (MF) are more fine and smooth, and worth hearing for many times. Medium-frequency (MF) and low-frequency (LF) are more pure and honest like an inexhaustible soft internal force, and especially flexibility of LF and positioning and width of sound field are obviously improved. This kind of damper-shackel is of top class at present.
