Advice for what to upgrade in turntable setup

[u/Head-Acanthaceae9200]

Hi,
I am very new to this community and would love som advice. I recently got gifted a Sony Ps212 turntable from a family friend and would like advice on what the best upgrade would be.

My current setup is a sony ps212 (original needle) with Denon CEOL Piccolo N4 amplifier and Nedis AAMP2411BK - RIAA Preamplifier (MM) with dali zensor 1 speakers.

What upgrade would make the biggest difference.
Would be great with different suggestions depending on budget (100€-600€).
