Stylus profiles for mono records


I have many original and first pressing mono records, mostly from Blue Note, Prestige, etc. These are 12" LPs pressed after 1952-54.

I am curious what stylus profiles are optimized for playing these sort of grooves? I would like to minimize surface noise as much as possible, but still have high fidelity.

.7 mil was the standard for microgroove recordings until the elliptical tip came to be. I tend to think that may still be preferred over anything else for monaural discs.
Unless you have any micro-groove records, you should be able to use any modern mono cartridge with a spherical, elliptical or fine line stylus. A true mono cartridge like the Denon DL-102 will provide you with 1-channel "true mono" output if you are using a single channel system.

If you will be playing these LPs through your stereo system, a "dual mono" cartridge like the Ortofon 2M Mono, the new Quintet Mono or the Cadenza Mono will provide 2-channel mono output. Several manufacturers also offer these cartridges: Audio Technica, Grado Shelter and others.
