Lightweight rigid headshell seems a good match to my vintage Shure. I am not equipped to give a scientific review but I replaced stock headshell on new mid end turntable with low end AT cartridge, for my vintage Shure V 15 V vmr ( also got nice replacement stylus here). Uses less tracking force than what I came with new turntable etc.) . So recalibrated tonearm and I an very pleased.
