Which cartridge for MMF-7


OK I need a new cartridge for my MMF-7. I think Ive narrowed it down to the following cartridges. Goldring Eroica (comes with the MMF-7), Grado Platinum, ot Clearaudio Audio Aurum Beta. These are in my budget. And they all have a 47k input which I need (Wright phono pre)
I know the Grado is warm. The Aurum Beta may be better. But are these cartridges a step up from the Goldring, a step down, or a step sideways?
