Grado Cartridge questions.....

I drive me Vandersteen 1C's with a Rogue Audio Cronus integrated amp (EL-34 tubes) and an NAD 533/Goldring Elektra (basically, a Rega Planar 2) front end. The table is plugged directly into the amp's phono input (built-in MM phono stage). The music sounds lovely, but..... I want to improve my analog set-up (the usual "upgrade itch").

I have heard that the Grado wood body cartridges match very well with my Vandy's and my amplifier. Most of my LP listening is "classic acoustic small ensemble" jazz (Miles, 'Trane, Rollins, Lee Morgan, Hank Mobley, Brubeck, Peterson, Lester Young, Hawkins, Messengers, Horace Silver, MJQ, etc.) So, finally, here are my questions :

1. Grado Platinum vs. Grado Sonata ?? The $200 difference is affordable.....is it worth it ?

2. Platnum/Sonata Reference vs. Platinum/Sonata Statement ??........The higher output Reference series would allow me to use my current built-in phono stage, whereas I would need an outboard phono stage (and the necessary issues of stage and interconnect decisions) for the Statement series. What's your opinion ??

3. What $ 1000 - $1500 table/arm combo to drive the cartridge ??... Rega ?, Project ?, SOTA ?, Music Hall ?....

I'd really appreciate your feelings and advice. Thanks, and Happy Listening !!
