I never wanted to use my "good" cartridge on records that were not designed for the cartridge..., I.e, modern cartridges since the LP came out, it seems to me, were perfected for 33rpm LP recordings...
For me, I found an Orofon Black 78 - i.e., a Modern Cartridge, designed to work well on 78rpm records.
It sounds great - to me...,
My parents gave me their collection of 78's, which, it turns out, have some very rare original recordings. Opera, Symphony, etc. Names like Caruso..., in all their "original" glory. They don't sound bad..., in fact, quite good with this cartridge. I run that on a Elac Miracord 770. All period peices for the source hardware, but then into a C-1, carver amps to the speakers.
I won't say it will hurt your 2m Red..., I don't know - but I do think it will sound better on a cartridge designed for 78s.
just my thoughts..., could be worthless, and someone else might actually (quite probably will) know more.
