hi Josh,
there are levels of performance for turntable packages like you have, and also for the individual parts of the whole system; platter/plinths, arms, cartridges, phono cables, and even phono cables. there are not strict dollar values to these steps, as price and performance are not exactly linear, and also vintage choices blur the performance ranks further.
in a very general sense, if your package is around $2000, then the next general level might be a total of $4000-$5000. at that level you would find a more solid sound, lower noise, and more musical nuance.
but the biggest part of vinyl sound is the pressings. with turntables the media has a much larger part of what you hear than the hardware. you do need to get to a certain point where you get ’over the hump’ with hardware first, and maybe your current level is not quite there yet. but it’s better in the long run to focus on the best pressings, than on hardware. your collection should drive the hardware investment, not the other way around.
maybe look at the spinner + arm as the next big step for you. so not just the platter.
