Dear @serge8 : As lewm said Grace F9 models always has a place in the vintage MM cartridges.
Now, if your JVC is the original named JVC not Victor ( Japan Victor Company. ) the Grace F9 can't competes. JVC and Victor were manufactured by JVC for the reason that still today I don't understand the JVC performs better than the Victor. The other issue is on the overall cantilever/stylus where some of the cartridges for sale on ebasy and other sources came with " fake " replacement stylus not original.
The other one that outperforms Grace is your AT model.
But as lewm said all those is in my room/system.
Regards and enjoy the MUSIC NOT DISTORTIONS,
