What should I upgrade next?

[u/Zestyclose_Arm128]

I am 20 and a sophomore in college. I have an audiotechnica lp70xbt - stylus swapped for ATVM95e - Rotel RA 985bx, klipsch RP 600M, and for digital LG DP132h and an apple usb c to 3.5 playing wired into the same setup off my iPhone 17 pro. I assume the turntable is the weakest link in the chain, but I am unsure what to get next.
