Mono Reissues and the Conical Stylus

Hi Folks,

Recently I started buying mono reissues from Speakers Corner, Impex, and have recently ordered a few from Analogphonic. They're all of the 'long haired' variety. In the process, I've come to discovery threads where posters claim that the newer mono reissue grooves are cut in a V (stereo) shape rather than the vintage U (mono) shape.
My AT 33 mono cartridge comes with a conical stylus and from what I can tell, so do the better mono cartridges, i.e. the Miyajima Zero Mono. This of course would then create an issue where it pertains to using a conical stylus in a V shaped groove.

Around November, I plan to purchase a Jelco tonearm for my modified Thorens TD 160 and after that, will be looking to upgrade to a higher end mono cartridge. However, I don't see that they're would be a viable solution to the stylus dilemma given that I will only have one tonearm. I do by the way own a collection of early mono records but would like to find a cartridge that better crosses over between my vintage pressings and my reissues. Any help is greatly appreciated. Thanks!

lewm, it would be unfortunate for you to be right concerning the Ortofon Cadenza mono, as this cartridge is at a good price point for what it claims to do. I've always been of the understanding that a true mono build is superior over a strapped stereo cartridge.

How exactly are mono records cut with a stereo cutterhead any different from those cut with a mono cutterhead?  The only difference I am aware of is the groove width / depth but the cutting stylus and groove profile is a "V" for both.

"If you're expecting 850-1000 hrs from a well polished nude conical Denon tip then how many hrs do you expect from Shibata or MicroRidge?"

My expectations, based on my experience, would be as follows:

1) 850-1000 out of a high quality nude conical.

2) 2,000-2,500 hours out of a high quality line contact or microridge.

Note the words "high quality". Not all conicals are created equal any more than all line contacts or microline styli are created equal.

But I have put those kinds of hours on a Denon 103R before retipping it, with no ill effects (and the cartridge still sounded good when retired) as well as the higher number on a couple of decent cartridges with good quality line contact and microline styli.

This assumes both:

1) playing vinyl that is both in very good condition and very clean

&

2) careful cueing practices

This is overestimated so much in my opinion, especially for nude high quality conical.

in my vision it is more or less like that:

300 conical

400-500 elliptical

600-800 shibata and line contact

1500-2000 for some micro ridge and microline

up to 2500 only for some exotic profiles like Replicant-100 or Gyger, VdH

Actually chakster, you're reiterating the dilemma. The post is about finding a stylus that works optimally with both 1940's /50's mono and mono reissues. The fact that a conical stylus is suited for early mono records is something that, I believe, we've gotten past. The discussion is about a stylus and cartridge that works for both old and new.

Sorry i have no experience in mono records from the 40's era. 

But i think you can get much better sound and overall better usability (long life span) with modern profiles playing new mono reissues or vintage mono from the 60's/70's. This is exactly what modern manufacturers recommend. I think you need at least two different mono cartridges or just two different mono styli (in case with mono mm cart) for records from the different era. You also need a phono stage with different RIAA curve for very old mono records as far as i know. The Gold Note phono stage has various RIAA curves.
