How to choose a cartridge?

You cannot go wrong with the Hana or the Ortofon 2m’s, in particular, the 2m Bronze.

I own both the Hana el and 2m Bronze, for the money they are two fantastic cartridges.... the 2m Bronze cartridge can accept the 2m black stylus for future upgrade. 

Stylus shape is also important. I've found that fine line generally dig deeper and get more subtleties. Of course they are generally more expensive

Channel separation and stylus shape, and cantilever material are all good.

The Link is to one of the many available Juergen's reviews of Cartridges, it has reasonable description to help see where the Cart's share and differ in the performance on offer.

Note: this is not a Cart' recommendation.

You can generalize a bit using various specs ( stylus profile, cantilever material, magnet type, coil materials, etc. ) however carts, being basically handmade transducers, are very much a product of the maker. I find it fascinating how different carts can sound despite using similar materials and techniques. 

For some this is the fun of it ( trying, learning )...
