FWIW, David Sager at the Library of Congress clued me into the playing Diamond Disks with a smaller stylus, even as small as 1.0 depending on the sound of the particular disc. If I remember right, you are liable to get more lower frequency noise with this method, but that's easy to cut out without losing any musical info.
It's been some years since I transferred any Edisons, so I lack further details. But it was almost always the case that an overly quiet disc performed better with a smaller stylus.

Subject: [ARSCLIST] Playing Edison Diamond discs
I am transferring Edison Diamond disks.
I'm using a Shure M44-7 with a 3.5 FCR stylus from Expert Stylus.
I think I've rewired the leads properly for a hill-n-dale groove.
The turntable is a Technics Quartz SL 1200 Mk 2.
I'm using a KAB Great Sound Escort pre-amp.
Still, the sound leaves much to be desired.
I'm having an extra hard time transferring the Liszt 2nd Hungarian Rhapsody p/b Rachmaninoff.
P.S. I strongly dislike that cadenza of Rachmaninoff! I don't think Liszt would have like it either.
