Linn Basik LVX to ?? for XX2 MkII

I just acquired a Dynavector XX2 to replace a 20XL. What an incredible upgrade! I loved the 20XL and don't know why I decided to upgrade, but I did and won't look back! The XX2 was like going from CD on an old Philips to SACD on an OPPO 95. Wow!

My current front-end consists of a Systemdek IIX with a 20mm acrylic platter, Linn Basik LVX tonearm and a Dynavector P-75 jumpered in "special" mode.

I'm only wondering if I would experience any substantial improvement by upgrading the arm. I'm playing with picking up a second hand Linn Ittok, which is basically a drop in replacement for the Basik, which would let me keep my armboard intact. I am also intrigued by the VPI JMW-9t, which would require a new armboard, or other arms (which would also require a new armboard).

I don't have the funds to upgrade the whole deck, or I'd probably go with a Scout 2 or something similar. I've got about $750 to get a used arm on the current deck.

Would it be a substantial upgrade to something, or should I just wait a few years until I have the funds to get a new table/arm?
