OK, I'm applying for a new membership in the retipper's club.
I salvaged an Ortofon FF15xeMkII with the tip from a Pfansteihl/Shure M75 replacement stylus ($6 from parts express). Used wood glue, bougainvillea thorn and a coating of nail polish on the joined cantilever. I don't even know if it's conical or elliptical. Tracking at 1.75 g.
Now this cartridge sounds better than any of my others (and some of them darn good too--Pickering XSV3000, AKG P8E, Shure ML140HE). Better imaging, depth, detail (almost too much detail!). How is this possible??
Next retip project: the Nagatron 350e.
One conclusion this leads me to, re: poor quality of aftermarket styli, that it's not the diamond that's the problem, it's more than likely the magnet they use--mismatched/generic type magnets that don't mesh electrically with the cartridge coils.
