Not to shift the focus of the thread but I thought I'd mention my experience with the F-9e, which I owned but sold, and the F-14, which I currently own.
I bought the F-9e as NOS, factory sealed, from LPGear maybe four years ago. With its stock stylus it was pretty OK to my ears, if a little closed in and unresolving relative to my stable of MC carts. It really had to be loaded at 100K to open up, and even then it didn't sound altogether right, becoming a little arch yet wispy. At 75K it was neither fish nor foul. Swapping in a Soundsmith CL, it definitely improved in all areas but remained less than fully satisfying. Don;t get me wrong: it was good into 100K, fundamentally natural if not quite properly balanced, at least in my system. Even with the improved stylus it was not a cartridge I would choose to play over others I own. So it went in the drawer.
I was intrigued enough by the Grace sound, however, to become curious about the F-14. I had read that the internal resistance was around half that of the F-9, which meant it would probably load naturally at 47K. Add better internal wiring, and it seemed highly promising. So when I found a sealed NOS unit without stylus (yes, they sold them that way) from a Japanese seller on eBay, I bought it, just to see. Right off, with the NOS F-9 stylus, it was better than the F-9. As I suspected, 47K was optimal loading. The SS CL improved on that, also as suspected. But not until I bought an OCL replacement did the F-14 really come into its own.
Now I find the F-14 to be a terrific performer, with all of the naturalness that I perceived in the F-9 but none of the drawbacks. It resolves like a good MC but seems more transparent. It's lively but carries weight. Excellent midrange. No real faults, though maybe doesn't dig as deeply into the bass as some MCs. Nonetheless, I can readily move from listening to MCs like A90, Benz Ebony L or TR, or SPU A95, e.g., without feeling a fall-off in fidelity, just hearing a different take on high-quality playback. Really nice.
