Hey man, I saw you posted this on RM as well, just didn't get a chance to reply yet. From LPgear.com, they don't mention the OM5, but this should roughly answer
Upgradeable Performance
All Super OM models have the same body, construction, and magnetic circuitry. The only difference is the interchangeable stylus unit. Thus, when your level of musical sophistication improves, you can simply switch the existing stylus to the Ortofon Stylus 30 or for pinnacle performance the Ortofon Stylus 40. The Stylus 40 offers pinnacle performance for the most demanding listener.
I think i'm gonna order than OM 20 you sent me the link for yesterday. It's cheaper than the OM 10 i was able to find as well.
