MONO cartridges


I bought a few Mono reissues and now I think about a proper cartridge for them.
But the information varies a lot, some write, for those reissues I don't need a mono cart., there would be no difference to a stereo cartridge, or the differences are not worth the price difference.
Next, are the modern mono cartridges only stripped down Stereo cartridges?
Half winding, half output?
How about the difference from the needle?
Are the "old" Monos the way to go? SPU?
I have a Lyra Helikon stereo running at the moment, that one is available as a Mono cartridge, or others too.... some experiences?
Thanks

I have compared EMT TMD25 with Benz Glider mono version on some older mono records. Glider was incorporated into the EMT TMD headshell. The results were, I prefer the TMD25. My interpretation is that the difference lies in the stylus dimensions, the TMD25 being 1mil (25mM) spherical, and the Glider, I assume, having the same stylus, as their stereo version. However, the difference may well be elsewhere. Sorry, I haven't tried playing newer mono records. Maybe, the Glider will shine with them.
I recently found a Sony XL55mono. It is in an integrated headshell, like the FR-7, and is quite heavy (though not quite as heavy as the FR-7). It is a low output MC cart. I have not found specs but I would put it in the 0.2-0.5mV area. It is something of a strange beast - it has a very thin cantilever and appears to run very light VTF despite its heavy mass. I have not found any literature on it and would welcome it if anyone had it.

In any case, it sounds very nice.

Note: it has a headshell ring to stylus tip length which is several mm shorter than the FR-7.
Jonathan,

You mention that the stylus is different on the Dorian mono than the Helikon. I have noticed that my Dorian Mono does not seem to handle surface noise that well. I have experimented with VTA endlessly to no avail and have just learned to live with it. I have read review after review and comment after comment about how great the Helikon is at ignoring surface noise and imperfections on older mono lps. This has not been my expierince with the Dorian.

I was wondering if you could elaborate on this at all. Does the Dorian perform differently than the Helikon in relation to surface noise and ignoring imperfections?

Thanks

Hi Syntax,
can send you my Airy-3X Mono if you want to try a Mono cart on your FR64s.
Bye,
