I’m in a similar situation, with roughly 400 late 70’s thru early 90’s vinyl and a Grado gold MM on a decent turntable / tonearm set-up but as much as I want to love it, I switch to Tidal and stream the same music and it’s just better…much better.
I consider going down the rabbit hole to upgrade my phono aspect of my system, but just don’t think the investment, which obviously would be several grand, is something I can justify….for what, to get it to sound “as good” as my digital setup?
unless I think it’d be better…..not sure I’m down with that.
