moving magnet cartridge suggestions for rp8?


Hello everyone I am currently looking at a new Rega RP8 turntable. My dealer is trying to sell it to me with the Apheta mc on it. But my cary Audio SLP-98p preamp only has moving magnet preamp built in. They keep telling me to buy a step up transformer. But I do not want to spend any more money on a $1000 transformer and more money on cables. Or ship it down to cary to upgrade the phono preamp.

So any suggestions on MM cartridges that would work marvellously with the Rega RP8?

Goldring Eroica high output MC. Works well in the Rega arms and you may not have to use a spacer at all. Maybe. Very nice cart for under a grand.
Does the Cary 98P use the octal base tubes? I'm thinking an AT150MLX, or AT150ANV if you can find one, would sound wonderful in combo.
