Swing headshell vs. standard headshell - 3D Frequency analyzer. Top: Standard headshell / Bottom: Swing headshell "This graph shows the result that the noises generated by tonearm resonance and external vibrations are being removed by the swing headshell." Noteworthy is that low frequency noise with high energy contaminates the pure signal across the entire spectrum. - signal amplification, offset, deformation, etc.
