Any comment about Ortofon, Empire, Grado Cartridges

[PTSOUNDLAB]

Hello,

does somebody have any experience, opinion, comment about these Cartridges :

1) Ortofon 510 MKII

2) Empire 2000 E/I

3) Grado Prestige Black

I would like to buy one for a Dual 1219 but I don't know what is the best

Thanks

Pascal.
