whell: I also read that on the GAR site - and I really wonder how they got that idea. Different versions in different countries? Or maybe a change in the series (could be, as it really is rather old now...), and that remark was true for some earlier versions? I don't know. However, I can assure you that it has already worked for lots of people without any problems.
But maybe you prefer another dealer website quote - then here's one from a well-established phono specialist over here in Berlin, namely PhonoPhono: "Im Vergleich spielt das Ortofon OMB10 viel ruhiger, löst besser auf und kann durch Nadeltausch (z.B. Nadel 20) erheblich aufgewertet werden." (means "In comparision the OMB10 plays a lot mellower, provides higher resolution and can be significantly upgraded by swapping the needle (e.g. Stylus 20).") Context is this buying advice page on good budget cartridges:
