I received the Empire 7755D stylus yesterday. I immediately noticed how thin the cantilever is — much thinner than I was expecting. I've never seen the Pfanstiehl 740-D7 in person, but photos on the web seem to depict a significantly thicker cantilever than the Empire counterpart.
The back of the package indicates "genuine replacement stylus for Fisher MG-57 cartridge, stylus ST-57," and doesn't mention any other carts/styli.
I wasn't familiar with the Fisher MG-57, so I Googled it. A UK web site called Stylus Plus indicates the following about the MG-57:
Original Cartridge No: MG-57
Original Stylus No: ST-57D
Stylus Type: Spherical Diamond
Cartridge Type: Induced Magnet
Tracking Weight: 1.25 Grams
If it's true that the MG-57 is an induced magnet body and the stylus is meant to track at 1.25g, that would suggest that it's very similar or perhaps identical to the 205LT body... and if the Empire 7755D is indeed an exact replacement for the ST-57 stylus, then it should therefore also be a direct replacement for the S205 stylus... yes?
