Any comments on the quality of replacement Stylus from Pfanstiehl


Has any one have any knowledge of replacement styluses from Pfanstiehl

If it's conical or elliptical, not a high end TT or system, it's probably as good as others, they have been around since before I was born.

what cartridge?

any reason not to move up to new cartridge, perhaps more advanced stylus shape?
