How Good Can My Vinyl Get?

So here is a question for turntable fans. I got back into vinyl recently, and so I decided to go with a budget starter table to see if it was for me. I got a UTurn Orbit Plus, with a pluto phono preamp and an Ortofon OM10 cartridge and have been really been enjoying it. It sounds very nice. eTotal outlay was about $500.

I suppose my question is...if I were to double, triple or even quadruple my initial investment, could i get a noticeably significant upgrade in sound quality or is it all just fractions of a degree past a certain point? I’m not talking about needing a $10k set of speakers to appreciate it kind of difference....i mean an improvement that makes you glad you spent the money.

How much scability exists in vinyl?
